Motion Detection Using the MSP430F2013 microcontroller using PIR sensor
Motion detection using pyroelectric passive infrared ( PIR) sensor elements is a
common method. Here a 16-bit Sigma-Delta ADC is integrated into the MSP430F2013 microcontroller in order to detect motion.

Hardware Design
A system capable of detecting motion using a dual element PIR sensor using the MSP430F2013 microcontroller. the MSP430F2013 provides all the
required elements for interfacing to the PIR sensor in a small footprint, Using the integrated 16-bit Sigma-Delta analog-todigital converter (ADC) and built-in front-end PGA (SD16_A). a simplified circuit that is used to process the PIR sensor output signal is shown. The
external components consist of the bias resistor, RB, required for the sensor and two RC filters
formed by R1/C1 and R2/C2. The R1/C1 filter serves as an anti-aliasing filter on the AX+ input.R2/C2 serves to create a DC bias for the AX- input. With a small
peak-to-peak sensor output of the PIR, , a higher gain setting is required eliminating the possibility that AX- can be tied directly to VSS.The sensor output signal after the antialiasing filter is connected to AX+. simple DC bias is established for maintaining the input range requirements of the SD16_A By heavily low pass filtering the sensor output before connecting to AX-.

Software Design:
analog sampling and data processing is
kept to a minimum required to reliably detect motion. If no motion was
detected in the last measurement the SD16_A internal reference is
enabled and a new conversion is started. After the conversion is complete, the SD16_A ISR is entered and the internal reference is disabled.
