Question

List mostly used sensors types in IoT

Answer 1

Mostly used sensor types in IoT are:

• Smoke sensor
• Temperature sensors
• Pressure sensor
• Motion detection sensors
• Gas sensor
• Proximity sensor
• IR sensors

Answer 2

The different types of sensors in IoT are: 

Sensor	Function
Temperature sensor	Measures the amount of heat energy in a source. Detects temperature changes and converts them into data.
Proximity sensor	It is responsible for the non-contact detection of objects near the sensor.
Pressure sensor	Measures the pressure changes in gases and liquids.
Humidity sensor	Measure the amount of water vapor in the atmosphere of air or other gases.
Motion detection sensor	It detects the physical movement (motion) in a given area and transforms motion into an electric signal.
Optical Sensor	Measures a physical quantity of light and converts rays of light into electrical signals.
Smoke sensor	It detects smoke (airborne particulates and gases) and its level.
Accelerometers	Measures an object’s linear acceleration based on vibration.
Gyroscope	It measures an angular position based on the principle of the rigidity of space.
