How do IoT sensors work?

IoT Sensors helps the ability to detect changes in the physical status of things is essential for recording changes in the environment. Wireless sensor technology plays a pivotal role in bridging the gap between the physical and virtual worlds and enabling things to respond to changes in their physical environment.

Sensors help to collect data from their environment, produce information and raising attention about context.

Some Key Factors About IoT and Sensors History:

1997: “The Internet of Things” is the seventh in the series of ITU Internet Reports at first launched in 1997 under the title “Challenges to the Network”.

1999: Auto-ID Center founded in MIT – Keven Ashton

2003: EPC Global founded in MIT

2005: Four important technologies of the internet of things was proposed in the WSIS conference.

2008: First international conference of the internet of things: The IoT 2008 was held at Zurich.

For Examples: Sensors in an electronic jacket can collect information about changes in external temperature and the parameters of the jacket can be adjusted accordingly.

What are types of sensors?

There are a lot of IoT sensors out there, some of which we use especially in the daily drive. Let us now say what they are.

These are some of the ones we use in most of them.

Temperature Sensor:

It is also know as smart temperature sensor. The temperature sensor is a device which is used for the calculating or measures the temperature or heat, such as Resistance temperature detectors (RTD ), thermocouple, thermistor, sensors, etc.

Proximity sensor:

The device that detects the presence or absence of a nearby object, it can be done using the electromagnetic field or radiation beam in which the field or return signal changes in the event of the existence of nearby objects.

Pressure sensor:

The device that senses pressure and converts it into an electric signal. depends upon the level of pressure applied.

water quality sensor
image source from

Water quality sensor:

The sensors help to detect the water quality and Ion monitoring primarily in water distribution systems.

chemical sensor
image source from

Chemical sensor:

The sensors are applied in several different factories. Their desire result is to indicate changes in liquid or to find out air chemical changes.

Gas sensor:

These sensors are similar to the chemical ones but are especially used to monitor changes in the air quality and detect the existence of different gases.

smoke sensor
image source from

Smoke Sensor:

The sensor is a device that detects smoke (airborne particulates and gases) and it’s level.

IR sensor
image source from

IR Sensor:

The sensor used to sense certain characteristics of its surroundings by either emitting or detecting infrared radiation.

Level Sensor
image source from

Level Sensor:

A sensor which is used to determine the level or amount of fluids, liquids or other substances that flow in an open or closed system is called a level sensor.

image sensor
image source from

Image Sensor:

Image sensors are tools which are used to convert optical images into electronic signals for displaying or storing files electronically.

Motion Detection Sensor
Image Source from

Motion Detection Sensor:

The motion detector sensor is an electronic device which is used to detect the physical movement (motion) in a given area and it transforms motion into an electric signal, motion of any object or motion of human beings.

Accelerator Sensor
Image Source from

Accelerator Sensor:

An accelerometer is a transducer that is used to measure the physical or measurable acceleration experienced by an object due to inertial forces and converts the mechanical motion into an electrical output.

Gyroscope Sensor
Image Source from

Gyroscope Sensor:

The device is very popular now a day, it is used in majorly in mobile phones and handheld devices.

Which is used to measure the angular rate or angular velocity is known as Gyro sensors, Angular velocity is simply defined as a measurement of the speed of rotation around an axis.

Humidity sensor
image source from

Humidity Sensor:

The presence of water in the air is called Humidity. The amount of water vapour in the air can affect human consolation as well as many manufacturing processes in factories.

The existence of water vapour also influences various physical, chemical, and biological processes.

Optical Sensor
Image Source from

Optical Sensor:

A sensor which measures the physical quantity of light rays and converts it into an electrical signal which can be easily readable by the user or an electronic instrument/device is called an optical sensor.
