IoT sensors form the core of many IoT systems, helping to collect data critical to their operations. Most IoT devices work using sensors that capture and analyze data to understand the physical environment around them. There are different types of sensors used to perform different jobs depending on the use case.
IoT sensor types
Currently, a wide variety of sensors are used in various applications. These sensors include proximity sensors, temperature sensors, chemical sensors, image sensors, gas sensors, etc. Let’s take a look at three sensor types that are widely used in multiple industries:
1. Gas sensor
Gas sensors are used to monitor changes in air quality and detect the presence of harmful gases caused by leaks or other conditions. They are mainly used in the oil and gas, manufacturing and pharmaceutical industries.
2. Temperature sensor
Temperature sensors are used to detect temperature changes. They are used in household appliances such as refrigerators, air conditioners, and thermostats, as well as in manufacturing industries that require machines to operate at certain temperatures. Temperature sensors can provide real-time information about machine temperature and the natural environment, helping to operate at optimal temperatures.
IoT sensors can provide critical information in real time that can impact work operations. If acted upon quickly based on the data provided by the sensors, it can help avoid disasters or help reduce losses, so IoT sensors and IoT devices are becoming increasingly popular in work and home environments. Soon they will become an integral part of our daily lives.
3. Proximity sensor
Proximity sensors are used to detect nearby objects. These sensors are mainly used in self-driving cars and autonomous robots in warehouses. Proximity sensors emit electromagnetic radiation, such as infrared, and detect changes in the return signal. Some types of proximity sensors include:
Inductive Sensors: These sensors use electromagnetic radiation to detect nearby metal objects.
Capacitive Sensors: Capacitive sensors are used to detect metallic and non-metallic objects through changes in amplitude caused by the object entering the electrostatic field of an electrode.
Photoelectric Sensors: Photoelectric sensors use light beams to detect the presence of objects. Since light can travel long distances, these sensors are used for long-distance sensing.IoT-gateway
