3.Service life: greater than 100000 times
4.Equipped with anti reverse connection protection, the reverse connection of the power supply will not burn the board
5.Capable of controlling equipment with AC voltage up to 220V10A or DC voltage up to 30V10A
6.Function Description
7.This module can detect the concentration of smoke, and can set one smoke detection threshold during use. When the smoke sensor detects that the ambient smoke concentration is greater than the set smoke threshold, the relay closes and the alarm indicator light lights up, and the buzzer sounds an alarm prompt. When the smoke sensor detects that the ambient smoke concentration drops below the set smoke threshold, the relay disconnects and the alarm indicator light goes out, and the buzzer stops alarming.

[1] Alarm buzzer
[2] Status indicator light, indicator light on, buzzer alarm, and relay closed (9 and 10 closed, 10 and 11 disconnected). The indicator light goes out, the buzzer stops alarming, and the relay is disconnected (9 and 10 are disconnected, 10 and 11 are closed).
[3] Smoke detection sensor, try to keep the smoke sensor close to the smoke as much as possible for more accurate detection
[4] The smoke concentration detection setting knob is rotated clockwise to provide a smoke concentration threshold; Rotate counterclockwise to lower the smoke concentration threshold.
[5] Power indicator light, permanently on after power supply
[6] Negative pole of power supply
[7] Positive pole of power supply
[8] The working power supply rotates, and the DC 5-7V pins are plugged in with a short-circuit cap, while the DC 7-30V pins are disconnected
[9] Normally open pin of relay
[10] Relay common pin
[11] Normally closed foot of relay
Package include:
1 x sensor
