Ultrasonic sensors have been a popular method for distance measurement and object detection for many years. Their basic operating principle works by measuring the amount of time it takes for their emitted ultrasonic pulse of sound to bounce off an object and return, hence the name ultrasonic sensor. With the market for autonomous robots, vehicles,…

Sensors are sophisticated devices that are frequently used to detect and respond to electrical or optical signals. A sensor converts the physical parameter (for example: temperature, blood pressure, humidity, speed, etc.) into a signal which can be measured electrically.Sensor can be defined as an element that senses in one form of energy to produce a variant in same or another form of energy. Transducer converts the measurand into the desired output using the transduction principle.There are various types of sensors like temperature sensor, IR sensor, touch, sensor, motion detectors, biosensor, accelerometer and many more. There are certain features which have to be considered while choosing a sensor.
