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 ....etc

This is a simple-to-use liquefied petroleum gas (LPG) sensor, suitable for sensing LPG concentrations in the air. The MQ-6 can detect gas concentrations anywhere from 200 to 10000ppm.

This sensor has a high sensitivity and fast response time. The sensor's output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.

This sensor comes in a package similar to our MQ-3 alcohol sensor, and can be used with the breakout board .This c ....etc
