Methane gas sensor module for Arduino MQ-4

Methane gas sensor module for Arduino and other microcontroller projects

This module has a sensitive methane sensor that will detect levels of methane in the air. The sensor outputs a varying voltage on the analogue pin depending on the level of methane and it has a comparator to give you a digital out at when the methane level reaches a certain level, this can be set with the built in potentiometer.

Please note, this sensor needs to warm up for 20 seconds before it will give a stable reading.

Voltage : 5VDC

Current : 150mA

Sensitivity : 300 to 10000ppm

Size 32x21mm

Alcahol Ethanol sensor module for Arduino and other microcontroller projects

A sensitive ethanol sensor will detect levels of alcahol in the air. The level of alcohol varies the output voltage. A comparator gives a digital output. When the ethanol level reaches a certain level, this can be set with the built in potentiometer.

Please note: this sensor needs to run for 24-48 hours before first time use

Voltage : 5VDC

Current : 300mA

Sensitivity : 0.4mg/L alcohol

Size 32x21mm
