ZE08 Electrochemical CH2O Formaldehyde Sensor Module

Description: 
ZE08-CH2O is a general-purpose and miniaturization electrochemical formaldehyde detection module. 
It utilizes the electrochemical principle to detect CH2O in the air which makes the module with high selectivity and stability. It is a built-in temperature sensor to make temperature compensation. 
It has the digital output and analog voltage output at the same time. It is a combination of mature electrochemical detection principles and sophisticated circuit design.
This module has high sensitivity and resolution and it also features low power consumption. 
Good stability, excellent ability of anti-interference and excellent Linear output are some other specifications of the ZE08 sensor.
In general, this sensor is used for CH2O detection, and it has some applications such as portable detector, air-quality monitor, air cleaner, air renewal system, air conditioner, and smart home.
