MQ-4 Natural Gas Methane Gas Sensor Module

LKR 310.00
In stock

1. Size: 32mm X22mm X27mm length X width X height
2. The main chip: LM393, ZYMQ-4 gas sensor
3. Operating voltage: DC 5 Volt

Suitable for home or factory methane gas, natural gas, and other monitoring devices.

1. Indication of the signal output.
2. Dual signal output (analog output, and TTL level output)
3. TTL output signal is low. (When low output signal light, and can be connected directly to the microcontroller)
4. 0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage.
5. Of methane gas, the natural gas has better sensitivity.
