Description

One size : 32mm X22mm X30mm L * 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 ( analog 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 , analog 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 .
