Product details

The Gravity CL2 chlorine sensor from DFRobot is an innovative, factory-calibrated device for measuring chlorine concentrations in the air, with a measuring range of 0 to 20 ppm. This sensor is characterized by its versatility, as it supports analogue, I2C, and UART output modes, allowing easy integration into various projects. The use of the electrochemical principle ensures high sensitivity, stability, and excellent resistance to interference. With a lifetime of more than two years, this sensor is a reliable choice for applications in the chemical industry, pharmaceutical production, and environmental protection. Compatibility with common microcontrollers such as Arduino, ESP32, and Raspberry Pi enables quick and easy integration into existing systems.

Features:

  • High sensitivity and accuracy in the detection of chlorine.
  • Supports multiple output modes: analogue, I2C, and UART.
  • Robust design with a long service life of over two years.
  • Strong anti-interference capability due to the electrochemical measuring principle.
  • Easy integration thanks to the Gravity interface and compatibility with Arduino, ESP32, and Raspberry Pi.

Application examples:

  • Monitoring the chlorine concentration in swimming pools and water treatment plants.
  • Use in the chemical industry for monitoring production processes.
  • Measurement of chlorine in the air in pharmaceutical production facilities.
  • Environmental monitoring for the detection of chlorine contamination.
