Code to utilize a PM2.5 sensor, OLED, and ESP8266
This project is an air quality monitor that uses a PM2.5 sensor and an SSD1306 OLED display to show real-time air quality data. The project is built using an ESP8266 microcontroller, Adafruit PM2.5 sensor, and a 128x32 OLED display.
- Measures and displays PM1.0, PM2.5, and PM10 concentration levels.
- Displays particle counts for particles larger than 0.3µm, 0.5µm, 1.0µm, 2.5µm, 5.0µm, and 10µm.
- Uses SoftwareSerial to interface with the PM2.5 sensor.
- Displays data on a 128x32 OLED display.
- ESP8266 microcontroller
- Adafruit PM2.5 sensor
- 128x32 SSD1306 OLED display
- Connecting wires
- PM2.5 Sensor:
- RX: D2 (GPIO4)
- TX: D4 (GPIO2)
- OLED Display:
- VCC: 3.3V
- GND: GND
- SDA: D1 (GPIO5)
- SCL: D3 (GPIO0)
The software is written in C++ and uses the Arduino framework. The following libraries are required:
- Adafruit GFX Library
- Adafruit SSD1306 Library
- Adafruit PM2.5 AQI Sensor Library
- SoftwareSerial Library
- Install the Arduino IDE from arduino.cc.
- Install the ESP8266 board package by following these instructions.
- Install the required libraries using the Library Manager in the Arduino IDE.
- Clone this repository or download the ZIP file and extract it.
- Open the
air_sensor_oled.inofile in the Arduino IDE. - Connect your ESP8266 board to your computer.
- Select the appropriate board and port in the Arduino IDE.
- Upload the code to your ESP8266 board.
Once the code is uploaded, the OLED display will show the air quality data in real-time. The data includes PM1.0, PM2.5, and PM10 concentration levels, as well as particle counts for various particle sizes.
