TOP 7 IOT SENSORS IN 2023

What are sensors and what applications exist?

A sensor is a device that takes input from its environment and then converts it into required information for humans. for example, the temperature sensor takes the signal from its environment and shows the output for humans.

There are many types of sensor which is used in our daily life. In the daily life of each department, you can find their usage for example They’re in our homes and workplaces, our shopping malls, our metro station, our smart grid station, and hospitals. They’re embedded in smartphones, laptops, smart LCDs, and smart DSLR cameras, and are an integral part of the Internet of Things (IoT). The sensor makes human life easier. It takes input from Environment, and processes, and shows the Output. the figure
below shows it        input output process

There are different shapes, and sizes of sensors in the market. There are many applications for IoT sensors. Here are 10 of the most popular types of IoT sensors in 2023.

HUMIDITY SENSOR

A humidity sensor is a type of sensor that measures the humidity from its environment and converts it into an electrical signal. The humidity sensor measures the amount of water vapour in the gasses and liquids. A humidity sensor is also called a hygrometer sensor that is used to measure moisture and air temperature from its environment. To Be remembered relative humidity is an important factor to measure comfort.

                                         HUMIDITY SENSOR
There are three types of humidity sensors:

👉Capacitive
👉Resistive
👉Thermal

Applications of humidity sensors

Humidity sensors are most often used in industries such as HVAC, biomedical, food processing, pharmaceuticals, meteorology, microelectronics, Smart grids, smart solar station, Civil, agriculture, and structural health monitoring.

Temperature Sensors

A temperature sensor is a device that detects and measures the hotness and coldness of an object. Have you ever left your laptop in your home in the summer? If so, your screen might have shown a warning that your Laptop has overheated. That is because there is a built-in temperature sensor that measures the temperature of your Laptop concerning the surroundings. Once the inside component reaches a certain temperature. the temperature sensor sends an electronic signal to an embedded computer that is used to process the whole signal. there are many types of examples you can find in your daily life.

👉Thermistors
👉RTDs                                                                       
👉Thermocouples 
👉Temperature Probes

Applications of Temperature Sensors

Temperature Sensor is widely used in many industries such that medical, pharmaceutical, motorsport, HVAC, agriculture, Domestic, industrial, aerospace, automotive, robotics, etc

Pressure Sensors

pressure sensor is a type of sensor that is used to convert a mechanical input pressure into an electrical output signal. The Relation between Pressure and voltage in pressure sensors is a direct relation.

There are two types of pressure one is absolute pressure and the other is the differential pressure. differential sensors are used to detect the pressure difference on a particular side of an object. Differential pressure sensors are used to monitor HVAC  to measure the airflow.

Pressure = Force / Area

Proximity Sensors

proximity sensor is a type of sensor that is used to detect the existence of objects without physical contact. A proximity sensor is a non-contact sensor which means there is no physical connection that detects the presence of an object. there are many types of sensors like electromagnetic fields, sound, light, and infrared radiation (IR), and Proximity sensors are used in assembly lines, phones, recycling plants, and self-driving cars. the two main types of pressure sensors used in daily life first are inductive and other is capacitive.

we used an inductive proximity sensor that can detect metal targets because their working principle is electromagnetic induction which is based on magnetic fields. on the other hand, Capacitive Proximity sensors can work only with metallic targets. proximity sensors are capable of detecting anything that can carry an electrical charge because their working principle is an electrostatic charge. Capacitive sensors are used in liquid-level detection for measuring liquid levels.

Types of proximity sensors:

👉Inductive Proximity Sensor. 
👉Optical Proximity Sensor.
👉Capacitive Proximity Sensor.
👉Magnetic Proximity Sensor.
👉Ultrasonic Proximity Sensor


Proximity Sensor

Applications of proximity sensors

Proximity sensors are used in smartphones, recycling plants,  smart self-driving cars, anti-aircraft systems etc

Level Sensors

A level sensor is a device that is designed to maintain and measure liquid levels. There are two types of level sensors: one is point level sensors and another is continuous level sensors. Point-level sensors show whether a liquid has reached a particular point or not. Continuous level sensors indicate and measure a continuous flow of liquid Level. we divide the level sensors into invasive sensors and non-contact sensors.
