SUNLEPHANT@MQ-4 Natural Gas Sensor Module / Methane Sensor Module

Description

First, the size: 32mm X22mm X27mm Second, the main chip: LM393, ZYMQ-4 gas sensor Third, the working voltage: DC 5 volt Fourth, features: 1, with a signal output indication. 2, dual signal output (analog output and TTL level output) 3, TTL output valid signal is low. (When the output is low when the signal light, can be directly connected to the microcontroller) 4, analog output 0 ~ 5V voltage, the higher the higher the higher the voltage. 5, the methane, natural gas has a high sensitivity 6, with long service life and reliable stability 7, fast response to recovery features Shipping List: 1 ¡Á Module
