10pcs 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:
10 x PCB board
10 x MQ2 sensor
10 x active buzzer
10 x 8P chip holder
10 x LM358 chip
10 x 5V relay
20 x KF3.96-2P terminal block
10 x 5MM green LED
20 x 5MM red LED
20 x 8050 triode
10 x 10K adjustable resistor horizontal
10 x 10 ohm resistor
40 x 2.2K resistor
60 x 10K resistor
10 x 104 monolithic capacitor
