Product Details
Adjustable Gas Sensor for - Hydrogen (H2), LPG, Methane-natural Gas (CH4), Carbon Monoxide (CO), and Alcohol. Detects 300-10,000PPM
MQ-5 liquefied gas Methane Gas Sensor Module
Overview
Suitable for home or industrial on LPG, natural gas, coal gas monitoring devices. Excellent resistance to alcohol, smoke interference.
Features
- Using high-quality dual-panel design, with power indicator and TTL signal output instructions;
- With a DO switch signal (TTL) output and AO analog signal output;
- TTL output valid signal is low. (When the output low signal light can be directly connected microcontroller or relay module)
- The analog output voltage, the higher the concentration the higher the voltage.
- For gas, natural gas has better detection sensitivity.
- There are four screw holes for easy positioning;
- Product Dimensions : 32 x 20 x 22
- With a long service life and reliable stability
- Rapid response and recovery characteristics
