Microcontroller to Sensor Interfacing Techniques

INTERFACING
Interfacing is a term used in electronics when different electronic devices are attached. The term is commonly used when attaching memory chips. Interfacing also often refers to the connection of peripheral devices to computers

MICROCONTROLLER

Overview

Micro-controllers are useful to the extent that they communicate with other devices, such as sensors,
motors, switches, keypads, displays, memory and even other micro-controllers.

Many interface methods have been developed over the years to solve the complex problem of balancing
circuit design criteria such as features, cost, size, weight, power consumption, reliability, availability,
manufacturability.

Many microcontroller designs typically mix multiple interfacing methods. In a very simplistic form, a micro-
controller system can be viewed as a system that reads from (monitors) inputs, performs processing and
writes to ( controls ) outputs.
