Description

What it is

The AQM 300E module is an air quality sensor designed to detect various gases and particulates based on odor. This device is ideal for integrating into DIY projects such as home or environmental monitors, using Arduino platforms.

Features

• Measures air quality based on odor
• Ideally suited for environmental monitoring projects with Arduino

What it is for

Serves to create an air quality monitoring system that sends real-time data to online platforms such as ThingSpeak. Compatible with Arduino.

Tutorial: How to use AQM 300E Module for Arduino

The AQM 300E module is an air quality sensor that detects various gases and particulates. Ideal for DIY projects such as home or environmental monitors.

What you need

• Arduino
• USB cable
• power supply (5V)
• serial monitor

Steps

1. Connect the AQM 300E module to the Arduino using a JST SH male pin cable
2. Power the module with 5V and GND
3. Connect the TX of the sensor to a digital pin of the Arduino (e.g., D2)
4. Install the AQM300E library or similar in the Arduino IDE software
5. Write a sketch that reads data from the sensor
6. Send the data to the serial monitor to view them in real-time
7. Verify the accuracy of the data with the sensor datasheet
8. Implement periodic reading and store the data on a database or a cloud platform

Example code

void setup() {
  Serial.begin(9600);
}

void loop() {
