T9 DC5V Humidity Sensitive Switch Relay Module Controller

T9 DC5V Humidity Sensitive Switch Relay Module Controller Description

Measurement of humidity, humidity sensor, humidity detection, with a relay output, direct power control equipment
using high-quality HR202 humidity sensor;
the comparator output directly drive the relay, the 220V AC or other equipment;
with a potentiometer to adjust temperature detection threshold
sensor interface can be arranged needle, with the lead of humidity sensor;

The circuit board size: 50x26mm, thickness 19mm, with four 3mm fixing bolt holes, easy to install
Contact normally open circuit connection:
Functional diagram connection is when the relay does not suck timely ,publicend and normally closed terminal is turned on, the equivalent of switching off, no power control equipment does not work, when the relay pulls in, the public end and normally open turning, equivalent switch is turned on, the device has power to work
Contact normally closed circuit connection:
Functional diagram connection is when the relay does not suck timely public side and normally closed terminal is turned on, the equivalent of the switch is closed, the circuit is turned on, the device has power to work, when the relay pulls in, the equivalent of switching off the device no electricity does not work
Electrical parameters:
Power supply voltage: 5VDC (default: 5V )
currents: 150mA
The maximum load: 250V 10A AC or 30V 10A DC, less than this power can be used
Colour:blue
Material:plastic
Size:50 x 26mm
