Size: 70 mm X50mm X20mm length * width * height
Second, the main chip: smoke sensor probe
Three, working voltage: DC 9 v
Four, features:
1, with a relay control output;
2, working current is small, low power consumption, induced current 30 ma, standby current: 10 ua;
3, with level detection alarm signal output can be effective control;
4. A copy of the power supply can be directly use DC9V batteries;
5, induction, high sensitivity, low rate of false positives;
6, effective insect resistance, resistance to dust, resistance to light effect, long service life;
7, large detection area, easy installation
Five, the application:
Suitable for residential home or commercial, such as indoor and outdoor smoke detection.
Module wiring label details:
GND - connect power anode
VCC - connect power anode
OUT - the default level signal output low level (smoke) output level is detected
K - often start relay output
G - relay output public side
B - relay output normally closed end
Test method:
3 s 1, hold down the test buttons, lights start flashing, relay suck together, often beginning with the public through.
2, blowing smoke into the maze, about 3 s lights began to twinkle, relay or absorption, relay often start with the public through;
