Characteristics of Hydrogen Sulfide Detection Sensor:

1 it has a signal output indication.

2 it consists of dual signal output (analog output and TTL level output)
The output signal of

3 its TTL is low. When the output is low and the signal light can be directly connected to the microcontroller

4 its analog output 0~5V voltage, the higher the concentration, the higher the voltage.

5 it can detect hydrogen sulfide, liquefied petroleum gas, natural gas, city gas, the smoke has good sensitivity.

6 it has long service life and reliable stability

7 it has the characteristic of fast response recovery
