Mq5 methane gas sensor methane detector module Arduino. Indication of the signal output. Dual signal output (analog output and ttl level output). Ttl output signal is low. (When low output signal light and can be connected directly to the microcontroller). 0 ~ 5v analog output voltage, the higher the concentration, the higher the voltage. Liquefied petroleum gas, natural gas, city gas, better sensitivity. Has a long life and reliable stability. Fast response and recovery characteristics. Applications: Liquefied petroleum gas, natural gas, coal gas monitoring device suitable for home or industrial. Excellent resistance to alcohol, smoke interference ability. Technical parameters: Size: 32x22x27mm. Main chip: Lm393, mq-5 gas sensor. Operating voltage: Dc 5v. Input voltage: Dc5v. Power: 150ma. Do output: 0.1v/5v. Ao output: 0.1-0.3a.
