MQ135 sensor Air quality sensor Hazardous gas detection
Size: 32mm X22mm X30mm
Main chip: LM393, MQ135 gas-sensing probe
Working voltage: DC 5V
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, the sulfides, benzene vapor, smoke and other harmful gases with high sensitivity;
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.
For the family, the environment of hazardous gas detection device, suitable for ammonia, aromatics, sulfur, benzene vapor, smoke and other harmful gases, gas detection, gas sensors tested concentration range: 10 to 1000ppm
Provide a reference routines, circuit diagrams and Other relative information.
