Intro: Pocket-CO Detector (Remake Edition)

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.

STEP 1: Prototype Build

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

STEP 2: ThinkSpeak

1. Create An account

2. Create a new channel

3. Customize the channel

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

STEP 3: IOT Coding

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

STEP 4: Flutter Coding

Flutter P-CO: https://github.com/UmaRasx/P-COFlutter-2.0

STEP 5: Prototype Test

Do a Test run with the code to ensure there are no broken things.

STEP 6: PCB & Wiring & Build

  1. cut the PCB to the desired size
  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 switch
  7. connect it to the Hostpot/wifi based on The IOT Code
  8. and voila.

STEP 7: Flutter +Thinkspeak Part 2

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

STEP 8: Extra File

In case of expired links, I decided to include the files
