4.4 Troubleshooting
Selama melakukan pengujian masih ada beberapa masalah atau kendala. Oleh karena itu, selama pengujian dilakukan juga troubleshooting.
4.4.1 Rangkaian Pemanas
Pada percobaan pertama yang dilakukan, pemanas tidak aktif. Lalu dilakukan troubleshooting dan terdapat kesalahan penyambungan rangkaian yang membuat pemanas tidak aktif. Maka dari itu rangkaian pemanas diganti dan dicoba sesuai dengan referensi yang didapat.
if (digitalRead(tombol4) == LOW) { goto timeStop;
while (digitalRead(tombol4) == LOW) { goto timeStop ;
Gambar 4.3Troubleshooting Rangkaian Pemanas
4.4.2 Rangkaian Kipas
Saat melakukan percobaan membuat rangkaian kipas pada protoboard, kipas sudah berfungsi. Dan saat rangkaian kipas dibuat pada PCB, ternyata kipas tidak berfungsi.
Setelah dilakukan troubleshooting ternyata arus dari transistor yang digunakan tidak cukup untuk mengaktifkan kipas. Maka dari itu rangkaian diganti dengan transistor yang arusnya lebih besar agar mampu menghidupkan kipas.
Gambar 4.4 Troubleshooting Rangkaian Kipas
4.4.3 Button tidak berfungsi
Saat pertama kali mencoba rangkaian button, button tidak berfungsi sama sekali, lalu melakukan troubleshooting ternyata kesalahan pada program (program tidak membaca button). Saat diubah program button pun berfungsi. Lalu saat semua program digabungkan button Up dan button stop tidak berfungsi, dilakukan troubleshooting terdapat kesalahan pada sambungan jumper antara arduino dengan button.
4.5 Pengujian Komponen
Pengujian komponen harus dilakukan untuk mengetahui ketepatan hasil dari komponen tersebut.
4.5.1 Sensor DHT22
Pengujian ini dilakukan untuk mengetahui apakah DHT22 dapat membaca suhu atau tidak. Setelah dilakukan pengujian, DHT22 berfungsi dan suhu yang ditampilkan oleh DHT22 adalah 28.90°C.
Gambar 4.5 Pengujian DHT22
4.5.2 LCD
Pengujian ini dilakukan untuk mengetahui apakah LCD dapat menampilkan karakter sesuai dengan tampilannya seperti menampilkan karaktek huruf dan angka.
Gambar 4.6 Pengujian LCD
4.5.3 Heater
Pengujian ini dilakukan untuk mengetahui apakah heater dapat berfungsi mengeluarkan panas atau tidak. Maka dari itu dilakukannya pengujian heater dengan menggunakan rangkaian heater dengan komponen seperti resistor, dioda, transistor BD139, dan relay 5V.
Gambar 4.7 Pengujian Pemanas
4.5.4 Kipas
Pengujian ini dilakukan untuk mengetahui apakah kipas dapat berfungsi atau tidak.
Maka dari itu dilakukannya pengujian kipas dengan menggunakan rangkaian kipas dengan komponen seperti resistor, dioda, transistor TIP3, dan power supply 12V DC.
Gambar 4.8 Pengujian Kipas Gambar 4.9 Pengujian Kipas
4.6 Pengujian Sistem
Untuk memastikan suhu alat bekerja dengan akurat, maka perlu dipastikan dengan melakukan pengujian dan perbandingan sensor yang akan digunakan dengan sensor suhu yang lainnya, maka dari itu dilakukannya perbandingan sensor suhu DHT22 dan DHT11 seperti pada tabel dibawah.
Tabel 4.1 Tabel Pengujian DHT22
Lalu dilakukan juga pengujian suhu yang tertampil di LCD dan suhu yang terukur.
Dalam pengujian ini kami menggunakan termometer untuk menguji suhu yang terukur pada box. Pengujian ini dilakukan untuk mengetahui apakah suhu yang dibaca sensor DHT22 akurat atau tidak. Berikut tabel pengujian suhu:

DHT11, DHT22 and AM2302 Sensors
Created by lady ada
Last updated on 2020-10-17 01:58:27 AM EDT
two parts, a capacitive humidity sensor and a thermistor (https://adafru.it/aHD). There is also a very basic chip inside that does some analog to digital conversion and spits out a digital signal with the temperature and humidity. The digital signal is fairly easy to read using any microcontroller.
DHT11 vs DHT22
We have two versions of the DHT sensor, they look a bit similar and have the same pinout, but have different characteristics. Here are the specs:
DHT11 (http://adafru.it/386) Ultra low cost
3 to 5V power and I/O
2.5mA max current use during conversion (while requesting data) Good for 20-80% humidity readings with 5% accuracy
Good for 0-50°C temperature readings ±2°C accuracy No more than 1 Hz sampling rate (once every second) Body size 15.5mm x 12mm x 5.5mm
4 pins with 0.1" spacing
DHT22 (http://adafru.it/385)/ AM2302 (https://adafru.it/uF2) (Wired version) Low cost
3 to 5V power and I/O
2.5mA max current use during conversion (while requesting data)
As you can see, the DHT22 (http://adafru.it/385) / AM2302 (https://adafru.it/uF2) is a little more accurate and good over a slightly larger range. Both use a single digital pin and are 'sluggish' in that you can't query them more than once every second or two.
You can pick up both the DHT11 (http://adafru.it/386) and DHT22 (http://adafru.it/385) or AM2302 (https://adafru.it/uF2) from the adafruit shop!
breadboard, perfboard or similar.
Likewise, it is fairly easy to connect up to the DHT sensors. They have four pins
1. VCC - red wire Connect to 3.3 - 5V power. Sometime 3.3V power isn't enough in which case try 5V power.
2. Data out - white or yellow wire 3. Not connected
4. Ground - black wire
Simply ignore pin 3, its not used. You will want to place a 10 Kohm resistor between VCC and the data pin, to act as a medium-strength pull up on the data line. The Arduino has built in pullups you can turn on but they're very weak, about

pin.
If you have an AM2302
little tricky to code it up, we suggest verifying the wiring and sensor work with an Arduino to start.
You should have the Arduino IDE (https://adafru.it/fvm) software running at this time. Next it’s necessary to install our DHT library, which can be done though the Arduino Library Manager:
Sketch→Include Library→Manage Libraries…
Enter “dht” in the search field and look through the list for “DHT sensor library by Adafruit.” Click the “Install” button, or “Update” from an earlier version.
IMPORTANT: As of version 1.3.0 of the DHT library you will also need to install the Adafruit Unified Sensor library, which is also available in the Arduino Library Manager:
Now load up the Examples→DHT→DHTtester sketch
If you're using a DHT11 sensor, comment out the line that sets the type:
//#define DHTTYPE DHT22 // DHT 22 (AM2302)
and uncomment the line that says:
#define DHTTYPE DHT11 // DHT 11
This will make the data appear correctly for the correct sensor. Upload the sketch!
You should see the temperature and humidity. You can see changes by breathing onto the sensor (like you would to fog up a window) which should increase the humidity.
You can add as many DHT sensors as you line on individual pins, just add new lines such as DHT dht2 = DHT(pin, type);
below the declaration for the initial dht object, and you can reference the new dht2 whenever you like.
To use the DHT sensor with your Adafruit CircuitPython board you'll need to install the Adafruit_CircuitPython_DHT (https://adafru.it/Beq) module on your board.
First make sure you are running the latest version of Adafruit CircuitPython (https://adafru.it/Amd) for your board. In particular for Gemma M0, Trinket M0, and M0 basic boards you must be running CircuitPython 2.1.0 or higher to have access to the necessary pulseio module!
Next you'll need to install the necessary libraries to use the hardware--carefully follow the steps to find and install these libraries from Adafruit's CircuitPython library bundle (https://adafru.it/zdx). Our introduction guide has a great page on how to install the library bundle (https://adafru.it/ABU) for both express and non-express boards.
Remember for non-express boards like the, you'll need to manually install the necessary libraries from the bundle:
adafruit_dht.mpy
You can also download the adafruit_dht.mpy from its releases page on Github (https://adafru.it/Ber).
Before continuing make sure your board's lib folder or root filesystem has the adafruit_dht.mpy module copied over.
Wiring
DHT wiring is very simple:
The left-most pin is power. We recommend powering from 5V (sometimes 3V is not enough) - this is OK even if you are using 3.3V logic
The second pin is data. Connect a 10K pullup resistor from this pin to 3.3V. If you are using a DHT11 it's required.
If you're using a DHT22 or AM2302 you can sometimes leave this off Skip the third pin
The right-most pin is ground
For the DATA pin you must pick a pin that has PWM support (pulseio) - Check the board's guide for what pins have timers available
In this example we'll use a Feather M0 and DHT22 sensor connected to pin D6
https://adafru.it/A0o https://adafru.it/A0o
Usage
To demonstrate the usage of the DHT sensor module you can connect to your board's serial REPL and run Python code to read the temperature and humidity.
Next connect to the board's serial REPL (https://adafru.it/Awz)so you are at the CircuitPython >>> prompt.
Next import the board and adafruit_dht modules, these are necessary modules to initialize and access the sensor:
having the 10K pull-up resistor to 3.3V volts)
Now create an instance of either the DHT11 or DHT22 class, depending on the type of sensor you're using (for the AM2302 sensor use the DHT22 class). You must pass in the pin which is connected to the signal line, for example a DHT22 or AM2302 sensor connected to board pin D6 would need this code:
dht = adafruit_dht.DHT22(board.D6)
Note for a DHT11 sensor you'd instead use adafruit_dht.DHT11 in place of the adafruit_dht.DHT22 code above.
At this point you're all set and ready to start reading the temperature and humidity! You can do this by reading the temperature property which returns temperature in degrees Celsius:
dht.temperature
To read the humidity grab the value of the humidity property, it will return the percent humidity as a floating point value from 0 to 100%:
dht.humidity
In most cases you'll always get back a temperature or humidity value when requested, but sometimes if there's electrical noise or the signal was interrupted in some way you might see an exception thrown to try again. It's normal for these sensors to sometimes be hard to read and you might need to make your code retry a few times if it fails to read. However if you always get errors and can't ever read the sensor then double check your wiring (don't forget the pull-up resistor if needed!) and the power to the device.
Example Code
Here's a full example sketch which also manages error-retry logic (which will happen once in a while.
Don't forget to change the logic pin to whatever pin you're using! Then save this as main.py on your CircuitPython board
while True:
try:
temperature = dht.temperature humidity = dht.humidity
# Print what we got to the REPL
print("Temp: {:.1f} *C \t Humidity: {}%".format(temperature, humidity)) except RuntimeError as e:
# Reading doesn't always work! Just print error and we'll try again print("Reading from DHT failure: ", e.args)
time.sleep(1)
If you are using a DHT11, change the code to use a adafruit_dht.DHT11(board.D2) object.
Open the REPL to see the output! Breathe on the sensor to see it move temperature and humidity up (unless you are a White Walker in which case the temperature will go down)
