Product Introduction
The SMD1007 hydrogen sulfide gas sensor is a MEMS micro gas sensor developed based on specific semiconductor gas-sensitive materials. It can be used to detect the hydrogen sulfide gas content in different scenarios.
The hydrogen sulfide gas sensitive material developed and made by IDM independently. When H2S gas contacts the sensitive material, the conductivity of the sensitive material will change. A specific test circuit can be used to convert the this change into an output voltage signal corresponding to the gas concentration.
Main Applications
It is widely used in the testing of hydrogen sulfide gas in scenarios such as
● Food testing
● Public sanitation
● Livestock
● Portable detectors
Sensor Characteristics
● Small size
● Low power consumption
● High sensitivity
● Fast response and recovery time
● Simple test circuit
● Good stability
● Long life time
