Product Description:
Applications:
A hazardous gas detection apparatus for the family, the environment.
Suitable for ammonia, aromatic compounds, sulfur, benzene vapor, smoke and other gases harmful gas detection. Gas-sensitive element
Test concentration range: 10 to 1000ppm
Package Included:
1 * MQ135 Gas Detection Module
- Main chip: LM393,MQ-135 gas sensor
- Operating voltage: DC 5V
- With signal output indicator instructions.
- Dual signal output (analog output, and TTL level output).
- TTL output valid signal is low level, (output low signal light, which can be accessed microcontroller IO port).
- Analog output with increasing concentration, the higher the concentration, the higher the voltage.
- with high sensitivity and good selectivity for Sulfide, benzene Department of steam, smoke and other harmful gases.
- Has a long service life and reliable stability.
- Rapid response and recovery characteristics.
- Size:36mm X24mm X25mm(L * W * H)
