Motion sensor is designed using PIR sensor and MSP430F2013.

Interfacing 8051 with GSM ADC_PCF and PIR sensor

pic16f with pirsensor

In this simple project, we’ll build a motion-sensing arduino alarm using a PIR (passive infrared) sensor and an Arduino microcontroller. This is a great way to learn the basics of using digital input ( the sensor) and output (in this case, to a noisy
