Product Name: ammonia gas detection sensor module
Semiconductor heating type - qualitative detection
Band simulation and TTL level signal output
The analog output voltage and concentration are linear, and the relationship is converted by the resistance ratio.

 

 


 

Module characteristic:
One, size: X40mm X28mm 35mm long * wide * high
Two, main components: ammonia gas sensor
Three, working voltage: 5V DC
Four, features
1, module level signal output, with alarm signal indicator;
2, sensor module with analog signal output, voltage range: 0-5V;
