3pcs DC 12V 50uA 3-Wire Human Body Induction PIR IR Pyroelectric Infrared Sensor Module Relay Control Output Sensing Distance 3-5m Load Capacity 100W High Level / Low Level

Features: Based on infrared technology, automatic control products, when someone enters switch sensing range, special sensors to detect changes in the human body infrared spectrum, switch automatically switches the load, do not leave the sensing range (who are active) the switch will continue to turn; person left, switch off automatically load delay. People to light, people from the lights out, kind convenient, safe energy. Specifications: 1. Bipolar design: three-wire connection, and the load capacity 100W 2. Automatic sensors: one to switch immediately turned (one event will last turn) who left after the delay off automatically. 3. Relay switch: can withstand high current output, high power load. 4. Automatic random delay (continuous delayed mode): People in the induction scope activity, the switch is always turned off automatically lose if the stationary switch off automatically. 5. Adjustable delay time: 10 seconds -350 seconds 6. Ultra Low Power: Switch own power
