Description:
Size: 32mm X22mm X30mm length * width * height
Main chip: LM393, NH3 gas sensing probe
Working voltage: DC 5V
Features:
1. It has a signal output indicator indication;
2, dual signal output (analog output and TTL level output);
3. The TTL output valid signal is low level; (when the output low level, the signal light is on, it can be connected to the IO port of the single chip)
4. The analog output increases with increasing concentration, and the higher the concentration, the higher the voltage;
5. High sensitivity and selectivity to ammonia;
6. Has a long service life and reliable stability;
7. Fast res ponse recovery features;
8. With mounting holes for easy installation;
9. The probe can be plugged and unplugged for easy testing.
Application:
Harmful gas detection device for home and environment, suitable for the detection of ammonia vapor, ammonia gas sensor test concentration range: 10 to 300ppm
Provide reference routines, circuit diagrams, and probe instructions
Package Included:
1 x MQ-137 Ammonia Sensor Module NH3 Sensor Module
