DS-HCHO-20 Formaldehyde sensor

The DS-HCHO-20 is a gas concentration sensor that incorporates both
electrochemical and semiconductor patterns. That is to integrate the
electrochemical module and the semiconductor module inside the sensor. The
electrochemical module is the main module, It uses a unique electrolyte
technology, and it has built in high-performance analog circuits and data
processing unit, integrated a large number of experience algorithms. A
semiconductor is a sub-module, Using it to improve the overall speed of the
sensor, and the signal of its output.The data of the main module are modified
with the corresponding algorithm, At the same time, the sensor is compatible
with the calibration curve of TVOC, which can output TVOC value at the same
time.

Main characteristics
 Electrochemical and semiconductor principles
 Real-time response
 Double mode check each other, Correct data
 Output TVOC value at the same time
