Winsen Electronics, produces sulfur dioxide/SO2 gas sensors, by measuring current based on the electrochemical principle, for industrial use. ME3-SO2 electrochemical sensor detects gas concentration by measuring current based on the electrochemical principle, which utilizes the electrochemical oxidation process of target gas on the working electrode inside the electrolytic cell, the current produced in the electrochemical reaction of the target gas is in direct proportion with its concentration while following Faraday law, then the concentration of the gas could be getting by measuring the value of current.

1 x Winsen ME3-SO2 Gas Sensor

Setup Guide

Identify the pins

Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.

Wire to your microcontroller

Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.

Install libraries

In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.

Upload example sketch

Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.

Calibrate if needed

Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
