Buy 5pcs Electronic DIY Kit MQ-2 Smoke Sensor Detector Natural Gas Alarm Components Kit Description: Working voltage: DC5V-6V Main components: MQ-2 smoke sensor, LM358 integrated chip Function: 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*59mm The module outputs a switching signal that can be controlled up to 220V 10A. Package included: 5 x PCB board 5 x MQ2 sensor 5 x active buzzer 5 x 8P chip holder 5 x LM358 chip 5 x 5V relay 10 x KF3.96-2P terminal block 5 x 5MM green LED 10 x 5MM red LED 10 x 8050 triode 5 x 10K adjustable resistor horizontal 5 x 10 ohm resistor 20 x 2.2K resistor 30 x 10K resistor 5 x 104 monolithic capacitor 5pcs Electronic DIY Kit MQ-2 Smoke Sensor Detector Natural Gas Alarm C
