Interfaces Grove PIR Motion Sensor with MSP430FR5969 Launchpad
-
This project interfaces PIR Motion sensor with MSP430.
-
LED will be turned on after detecting Raising Edge interrupt from Sensor and will be switched off by WDT.
-
The LED on period can be controlled by configuring WDT in WDTInitialisation.c
-
Sensor gives 3.5V output(Logic 1) if Vcc is 5V. Below 5V, sensor is behaving erratically. Make sure you give 5V at Vcc pin
-
If you want to change Pin to which sensor is connected, please make appropriate changes in ISR.
