Pocket-CO Detector

Hello Everyone, My name is Umar Kharits Al Khikam (2502048022) and I'm a second-year student at Binus University studying Computer Engineering.

Vision:

•To keep track of the CO quality of a room, I propose a pocket CO quality device that can measure the CO quality of a room's air.

1, Kabel Tunggal Jumper Panjang 1M x 8Warna

2. ESP32 DevKitC V4

3. Kabel Micro USB to USB ESP32

4. Battery 18650 Shield 1 Cell

5. Breadboard 400 Tie Point

6. LCD OLED 0.96 WHITE I2C

7. pcb bolong ic 18,5x7,2 cm

8. Sensor Carbon Monoxide MQ-7

9. Case

1. connect ESP32 DevKitC V4 34 pin to MQ-7 SENSOR-A0 pin

2. connect ESP32 DevKitC V4 VCC/3V3 pin to MQ-7 SENSOR VCC pin

3. connect ESP32 DevKitC V4 GND pin to MQ-7 SENSOR GND pin

4. connect ESP32 DevKitC V4 22 pin to WHITE I2C SCL pin

5. connect ESP32 DevKitC V4 21 pin to WHITE I2C SDA pin

6. connect ESP32 DevKitC V4 VCC/3V3 pin to WHITE I2C VCC pin

7. connect ESP32 DevKitC V4 GND pin to WHITE I2C GND pin

1. Create A account

2. Create a new channel

3. Customize the channel

4. Grab Write API KEY and apply it to the IOT code.& Flutter code

IOT P-CO: https://github.com/UmaRasx/IOT-P-CO

Flutter P-CO: https://github.com/UmaRasx/flutter-P-co

Do a Test run with the code to make sure no broken things.

1. Snap the PCB to half
2. trim and place the esp32,l2c,mq-7
3. Connect with wiring to the right pin
4. buy a case, or build one
5. Assemble
6. turn on the on switch
7. connect it to the Wifi
8. and voila.

Run the Flutter app or open thinkspeak to see the result.
