ماژول گاز هیدروژن MQ-8
Overview
This sensor module has an MQ-8 as the sensor component and has a protection resistor and an adjustable resistor on-board. The MQ-8 gas sensor is highly sensitive hydrogen and less sensitive to alcohol, and cooking fume. It could be used in gas leakage detecting equipments in family and industry. The resistance of the sensitive component changes as the concentration of the target gas changes.
Features
Continuous Analog output
3-pin interlock connector
Low cost and compact size
