Question

How does a sensor work? Describe its usages at various places.

Answer 1

Answer:

Explanation:

Sensor - Sensor is a device which converts non-electrical, physical or chemical quantity into an electrical signal. Sensors measure something which is called as Measurand. Sensors are also called as Transducers. ... Small changes in the measured signal volume are also converted into electrical signals.

   Different Types of Sensors

Temperature Sensor.

Proximity Sensor.

Accelerometer.

IR Sensor (Infrared Sensor)

Pressure Sensor.

Light Sensor.

Ultrasonic Sensor.

Answer 2

Sensor work:

A sensor transforms stimuli such as heat, light, sound, and movement into electrical signals. These signals are transferred through an interface that changes them into a binary code and transfers this on to a computer to be processed. It converts non-electrical, physical or synthetic quantity into an electrical signal. Every sensor has a distinct principle of operation, based on the type of physical quantity it is measuring. The idea is to generate a variation in the properties of the sensor (such as resistance, density, shape, temperature, etc) as a function of the physical quantity under measurement. Sensors are also called as Transducers.

Uses of sensor work:

• Light sensors are utilized in cameras, infrared detectors.
• Magnetic Field sensors are employed for potential steering, security, and current measures on transmission lines.
• Ultrasonic sensors are used for ground measurements.
• There are various kinds of sensors to identify the  rate of speed like speedometers, LIDAR, doppler radar, airspeed indicators, pitot tubes
