MQ-131 O3 ózon gázérzékelő modul

Suitable for detection of harmful gases such as ammonia, aromatic compounds, sulfide, benzene vapor, smoke and other gases, gas-sensing components Test concentration range: 10 to 1000ppm

Module Features:
1, the use of high-quality double-panel design, with power supply instructions and TTL signal output instructions;
2, with a DO switch signal (TTL) output and AO analog signal output;
3, TTL output valid signal is low. (When the output signal is low when the light can be directly connected to the microcontroller or relay module)
4, the analog output 0 ~ 5V voltage, the higher the voltage the higher the concentration.
5, the air quality, harmful gas detection has better sensitivity.
6, there are four screw holes to facilitate positioning;
7, the product dimensions:32mm (length) * 22mm (width) * 27mm (height)
8, with long-term service life and reliable stability
9, rapid response to recovery characteristics
10, the working voltage: 5V
