ZE03-CL2 Gas sensor can be used to measure Chlorine gas concentration in the atmosphere. This is an Industrial-grade sensor and is very easy to interface to your Microcontroller, Arduino as well as Raspberry Pi as they have linear Analog output as well as UART output (3 volts).
ZE03 Series of Gas Sensor Modules by Winsen is a general-purpose and high-performance electrochemical module. It uses three electrodes, an electro-chemical gas sensor, and a high-performance microprocessor. By using this GAS Sensor you will be able to Monitor the concentration of Chlorine gas.
It is with built-in temperature sensor to make temperature compensation, which makes it more accurate to detect Chlorine gas concentration. It has the digital output as well as analog voltage output at the same time which facilitates the usage and calibration and shortens the development period. It is a combination of mature electrochemical detection principles and sophisticated circuit design, to meet customers different detection needs.
