HR202 DC 5V 1 Channal 1CH Humidity Sensor Switch Relay Module Control Board Humidity Sensor Module for Arduino

·DC 5V 1-Channel Relay interface board.

·Indication LED for output,can be directly output signal chip microcomputer control.

·The humidity sensor is the most sensitive to the environmental humidity and is generally used to detect the ambient humidity;

·modules,environment humidity more than set threshold,relay,absorption and often start through public end,and when the environment humidity is lower than the setting threshold,relay disconnect, public end with normally closed end connected;

·The common end,normally open and normally closed three ports are equivalent to a double control switch. When the relay coil is energized, the common end and the normal start lead are connected; when there is no electricity,the common end and the normally closed end are connected.

Product Parameters

·Power supply voltage: 5VDC;

·Current: greater than 150mA;

·Maximum load:250V 10A ac or 30V 10A dc,less than this power can be used.

High quality HR202 moisture sensor;

·The comparator outputs a direct drive relay,which is connected with 220V ac or other equipment;

·Equipped with potentiometer to adjust the temperature detection valve value;

·The sensor interface can be equipped with row needle and wet sensor with lead wire;

·Shape and size of circuit board:50x26mm,19mm thick,with 4 3mm fixed bolt holes for easy installation.
