Sensors play a vital role in safety systems. They can sense and respond to various environmental parameters, such as temperature, humidity, pressure, light, etc., to ensure the safe operation of the system. Below we will describe in detail the common sensors in security systems and their classification.

1. Temperature sensor

A temperature sensor is a device used to measure temperature, which is able to convert temperature changes into electrical signals or other forms of signals so that the system can operate accordingly. In safety systems, temperature sensors are usually used to monitor the temperature of the equipment while it is running, preventing failures caused by too high or too low temperatures.

2. Pressure sensor

A pressure sensor is a device used to measure pressure, which is able to convert pressure changes into electrical signals or other forms of signal so that the system can operate accordingly. In safety systems, pressure sensors are usually used to monitor the pressure of hydraulic, air pressure and other systems to avoid failures caused by too much or too little pressure.

3. Humidity sensor

A humidity sensor is a device used to measure the humidity of the air, which can convert the humidity change into an electrical signal or other form of signal, so that the system can operate accordingly. In the security system, the humidity sensor is usually used to monitor the humidity of warehouses and equipment rooms to prevent faults caused by high or low humidity.

4. Light sensor

A light sensor is a device used to measure the intensity of light, which can convert the light change into an electrical signal or other form of signal, so that the system can operate accordingly. In security systems, light sensors are often used to monitor the light intensity of places such as roads and parking lots to help improve visual recognition and monitoring capabilities.

5. Speed sensor

A speed sensor is a device used to measure the speed of motion, which is able to convert the speed change into an electrical signal or other form of signal so that the system can operate accordingly. In the safety system, the speed sensor is usually used to monitor the movement speed of vehicles, personnel, etc., to prevent failures caused by too fast or too slow speed.

6. Weight sensor

A weight sensor is a device used to measure the weight of an object, which is able to convert the weight change into an electrical signal or other form of signal so that the system can operate accordingly. In safety systems, weight sensors are usually used to monitor the weight of Bridges, buildings and other structures to prevent structural damage caused by overload.
