PIR Controlled Relay : 4 Steps - Instructables

Step 3: SCHEMATIC. We interface the IR Motion sensor “OUT” to Pin 4 and the Relay “IN1″ to Pin 8. The light has one of the 120V wire grafted to associate the end associated with the power attachment to the COM (Common) Pin of the Relay module and the one heading off to the light is associated with the NC (Normally Closed) Pin.

PIR SENSOR -

2020-12-29· This project is an automatic PIR sensor. DESCRIPTION . Project is based on Holtek s IC HT7610A, which is a CMOS LSI chip designed for use in automatic PIR lamp, flash or buzzer control. It can operate in 3-wire configuration for relay applications. In our project we have used relay instead of Traic to connect any kind of load in output, HT7610B IC is suitable for traic and HT7610A for Relay ...
