Specification

 

Size: 32mm x 22mm x 30mm

 

Main chip: LM393, NH3 gas-sensing probe

 

Working voltage: DC 5V

 

Characteristics:

               1, with the signal output LED indication;

               2-way signal output (analog output, and TTL-level output);

               3, TTL output valid signal is low; (low output signal light, which can be accessed microcontroller IO port)

               4, analog output increases with the concentration, the higher the voltage the higher the concentration;

               5, ammonia has a high sensitivity and selectivity;

               6, with a long life and reliable stability;

               7, Fast response characteristics;

               8, with mounting holes for easy permanent installation;

               9, the probe can plug design for easy testing.

 

Application:

     For the family, the environment of hazardous gas detection device, suitable for the detection of ammonia vapor, ammonia gas sensors tested concentration range: 10 to 300ppm

 

Provide a reference routines, circuit diagrams and Other relative information.

 

Package Included:
