Microcontroller Interfacing – Sensors

image-2292
Microcontrollers have become very useful in embedded design as they can easily communicate with other devices, such as sensors, switches, displays, keypads, motors and even other microcontrollers. A microcontroller is basically used as the brain or intelligent processing unit to control other devices connected (interfaced) to it in embedded systems just like a PLC is in industrial automation. Interfacing a device with a microcontroller in simplest terms simply means to connect a device to a microcontroller. This article will make it easier to anybody with very limited experience in electronics to learn how to interface different sensors widely with a PIC Microcontroller.

Digital Barometer using PIC Microcontroller and MPX4115A Pressure Sensor – XC8

The MPX4115A is an atmospheric pressure sensor powered by 5V and delivers and output from ~0.25V to ~4.75V based on the pressure detected at room temperature (25°C). The device provides a linear output based on pressure. It can measure pressures between 15kPa and 115kPa. Note that 1 atmosphere of pressure at sea level is equal to 101,325 Pa or 101 kPa. This sensor is ideal for microcontroller based barometer, altimeter, data logger or weather station applications. In this article, we're gonna create a simple Digital Barometer using MPLAB XC8 compiler.
