Description Project is based on Holteks 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 […]
Today we are simple going to interface PIR with PIC Microcontroller PIC16F877A. In this circuit if some moving objects comes in the range of PIR sensor, the buzzer will start beeping. Material Required PicKit 3 PIR Sensor. PIC16F877A IC 40 – Pin IC holder Perf board 20 MHz Crystal OSC Female and Male Bergstick pins 33pf Capacitor
