RhydoLabz s LPG Gas Sensor Module is designed to detect the presence of a dangerous LPG leak in your Home, car or in a service station, storage tank environment by interfacing with Microcontroller without ADC Channels and programming. In this version of LPG Gas sensor module two pots are included, one for trigger level setting and the other for setting sensitivity of the sensor. It allows to determine when a preset LPG gas level has been reached or exceeded. The module uses MQ-6 sensor to sense LPG leak. The MQ-6 can detect gas concentrations ....etc

Abstract

A keypad consists of 3 columns and 4 rows, hence the name, whenever the user taps one button, the column and the row corresponding to that button are shorted, for example, if a user chooses to tap the 5 button, col2 and row2 are shorted, if a users picks 0 button, col2 and row4 are shorted, and so on.

So how do you read a keypad using a Microcontroller?
the method used to read such input is called Scanning, you connect the rows and the columns to the microcontroller, you set the columns as outputs, rows as inputs (or vice versa) ....etc

The are many cool sensors available now a days, ranging from IR distance sensor modules, accelerometers, humidity sensors, temperature sensors and many many more(gas sensors, alcohol sensor, motion sensors, touch screens). Many of these are analog in nature. That means they give a voltage output that varies directly (and linearly) with the sensed quantity. For example in LM35 temperature sensor, the output voltage is 10mV per degree centigrade. That means if output is 300mV then the temperature is 30 degrees. In this tutorial we will learn how ....etc

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
