Description
PCB Size:6.2*3.6cm
Material:Metal+Plastic
This circuit can be powered by a 5-7.5V DC power supply.Switch S1 is the power switch, resistor R1 and LED D1 are used for power indication.Sensor MQ-3 needs to be heated to a certain temperature during operation,so there is a section of electric heating wire installed inside,and resistor R4 is the current limiting resistor of the electric heating wire.It is normal for MQ-3 to heat up after being powered on
