Ammonia detection sensor MQ137 NH3 gas sensor module large price advantages

Our shipping with the pass , rhyme delivery , in the pass , rhyme remote areas unreachable . Not shipping in the column.

One size : 32mm X22mm X30mmL * W * H

Second, the main chip : LM393, NH3 gas sensing probe

Third, the working voltage : DC 5V

Four characteristics:

1, with the signal output LED indicates ;

2 , dual signal output ( - output , and TTL level output ) ;

3, TTL output valid signal is low ; ( lights lit when the output is low, which can be accessed microcontroller IO port )

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

5 of ammonia with high sensitivity and selectivity ;

6, with a long life and reliable stability ;

7 , rapid response and recovery characteristics ;

8 , with mounting holes for easy fixed installation ;

9 , the probe can plug design for easy testing .

V. Application :

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