A proximity sensor is a device that is capable of detecting the distance between two objects and controlling or driving an actuator according to preset limits. Therefore, it has a wide range of uses in many fields.

Most of the thermal resistances are made of pure metal materials. Currently, platinum and copper are the most widely used. In addition, thermal resistances such as nickel, manganese and tantalum have been used.

In modern industrial production, especially in automated production processes, various sensors are used to monitor and control the various parameters of the production process, to operate the equipment

The linear range of the sensor is the range in which the output is proportional to the input. In theory, within this range, the sensitivity remains constant. The wider the linear range of the sensor, the larger its

The light sensor is composed of two components, a light projector and a light receiver. The light is focused by the lens by the light projector, transmitted to the lens of the light receiver, and then to the receiving

Mounting a light emitter and a receiver face to face on either side of a slot is a trough optoelectronic. The illuminator emits infrared or visible light, and the light receiver receives light in an unobstructed condition.
