Sensors

1. Ultrasonic Sensor

   • It uses a transducer to generate ultra sonic signals and receive them and then determine the distance

2. IR Sensor

   • It consists of a transmitter and a receiver. It works by emitting infra red rays. If the rays are reflected and received back, it signifies the presence of an obstacle
     • It is used in mobile phones, remotes, etc.

3. Temperature Sensor

   • Works by generating electrical signal under the influence of heat and cold
     • It is used in air conditioners, mobile phones, microwave, etc.

4. Proximity Sensor

   • It works by emitting radio-active signals. It is used to detect motion
     • It is used in mobile phones

5. Level Sensor

   • It measures the level of liquid
     • Point Level
       • The result is classified into levels like high, medium or low
     • Continuous Level
       • The result shown is exact measurement and is highly accurate

6. Smoke and Gas Sensor

   • It detects smoke and gases like Carbon di-oxide
     • It is used in Fire Alarm Systems and Smoke detectors

7. Touch Sensor

   • Works by opening and closing a circuit. Whenever the sensor is touched or pressure is applied, the circuit closes and current flows
     • It is used in mobile phones, tablets, etc.

8. Pressure Sensor

   • Works by measuring the compression of water or air
