ZE21-CS is a special-purpose and miniaturization electrochemical module. It utilizes the electrochemical principle to detect Battery liquid volatile gas and the detection gas generated when the battery burns burning gas, which makes the module with high selectivity and stability. The built-in temperature sensor can do temperature compensation, and it has digital output and analog voltage output. It is a combination of mature electrochemical detection principles and sophisticated circuit design.
Application:

Detection of battery leakage gas CO, H2, etc. in electric vehicle EVs battery boxes, new energy storage and other occasions.


Features:

  1. High sensitivity
  2. High resolution
  3. Low power consumption
  4. Long life
  5. Uart output

Package Includes:

1 x Winsen Battery Leak Detection Module ZE21-CS

Setup Guide

1
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.
2
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.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
