5pcs Electronic DIY Kit MQ-2 Smoke Sensor Detector Natural Gas Alarm Components Kit

Description:Working voltage: DC5V-6VMain components: MQ-2 smoke sensor, LM358 integrated chipFunction: Detecting liquefied gas, propane, hydrogen, natural gas, and other combustible gases. When flammable gas is detected, the red light is on, the buzzer sounds, and the relay acts. The three are activated at the same time. The probe needs to be warmed up for 1 minute, so it will work normally after 1 minute of power on.Module size: 36*59mmThe module outputs a switching signal that can be controlled up to 220V 10A.Package included:5 x PCB board5 x MQ2 sensor5 x active buzzer5 x 8P chip holder5 x LM358 chip5 x 5V relay10 x KF3.96-2P terminal block5 x 5MM green LED10 x 5MM red LED10 x 8050 triode5 x 10K adjustable resistor horizontal5 x 10 ohm resistor20 x 2.2K resistor30 x 10K resistor5 x 104 monolithic capacitor
