As of now, I have shared little knowledge about IOT in my articles. Now I will let you know about various types of sensors used in IOT.
What is a Sensor? 🤔
Sensor is just a device that senses the physical activities in your environment and then convert them into electrical signals.
Types of Sensors:
- Mechanical sensors
- Magnetic sensors
- Thermal sensors
- Radiation sensors
MECHANICAL SENSOR: 👇
Mechanical sensors are used to measure variables such as position, velocity, acceleration, force, pressure, levels (such as a liquid in a tank), and flow.
- Pressure sensor
- Flow sensor
PRESSURE SENSOR :- A pressure sensor is a device for pressure measurement of gases or liquids. A pressure sensor usually acts as a transducer; it generates a signal as a function of the pressure imposed.
FLOW SENSOR :- An electronic device that measures or regulates the flow rate of liquids and gasses within pipes and tubes. Flow sensors are able to detect leaks, blockages, pipe bursts, and changes in liquid concentration due to contamination or pollution.
MAGNETIC SENSOR: 👇
A sensor which is used to notice disturbances as well as changes within a magnetic field such as strength, direction, and flux. These are used to measure current, speed, position and displacement.
THERMAL SENSORS 👇
Thermal sensors are used to measure temperature. Thermal sensors are found in many laptops and desktop PCs in order to sound an alarm when a certain temperature has reached.
- Thermocouples
- RTDs
- Thermistors
Thermocouples :- Thermocouples are the most commonly used temperature sensors due to some features like a wide temperature range from below -200°C to over 2000°C, accurate, and are relatively low-cost.
Resistive Temperature Detectors :- The term RTD stands for “Resistive Temperature Detector” is an electrical resistance temperature sensor that is made of coils of metals or films like platinum whose electrical resistance is a role of temperature.
Thermistor :- The thermistor is a temperature sensing device that changes the physical resistance with the temperature.
RADIATION SENSOR 👇
A radiation sensor is a device for measuring nuclear, electromagnetic or light radiation.
OTHER TYPES OF SENSORS:
🔹Proximity sensor
🔹Gas sensor
🔹Ultrasonic sensor
🔹Water level sensor
🔹Smoke sensor
🔹Raindrop sensor
🔹PIR sensor
🔹Humidity sensor
🔹Image sensor
🔷PROXIMITY SENSOR :- detects the presence of an object in your way.
🔷GAS SENSOR :- detects the presence or concentration of gases in the atmosphere.
🔷ULTRASONIC SENSOR :- measures the distance of a target object by emitting ultrasonic sound waves
🔷WATER LEVEL SENSOR :- detects the level of water in storage tanks.
🔷SMOKE SENSOR :- senses the presence of smoke, as a key indication of fire, and sounds a warning to building occupants.
🔷 RAINDROP SENSOR :- used for sensing rain.
🔷PIR SENSOR :- Passive Infrared motion sensors are designed to reliably detect people, large pets & other large warm moving objects.
🔷HUMIDITY SENSOR :- measures the humidity in its environment and converts its findings into a corresponding electrical signal
🔷IMAGE SENSOR :- detects and conveys information used to make an image.
I hope this article will be little bit knowledgeable for you. Merci beaucoup 😊
