Microwave sensor is a device that uses microwave characteristics to detect some physical quantities. Including the presence of sensing objects, moving speed, distance, angle and other information.

With new materials and processing technology, the infrared detection rate of the pyroelectric infrared sensor is increased, the response wavelength is increased, the response time is shortened, the pixel sensitivity and pixel density are higher, the interference is high, and the production cost is r......

With the advent of the new technological revolution, the world has begun to enter the information age. In the process of using information, the first thing to be solved is to obtain accurate and reliable information, and sensors are the main ways and means to obtain information in the fields of natu......

We need to know what is the difference between these two gases. Combustible gas means that it can be uniformly mixed with air or oxygen within a certain concentration range to form a premixed gas.

The infrared human body sensor lamp is designed with imported technology MCU circuit, active infrared working mode, with good stability, strong anti-interference and other characteristics, with infrared decoding method, widely used in demanding commercial and industrial occasions. It is a new genera......

Confirm the voltage. Turn off the power before installation. The power cord is connected to 220VC, 50 (HZ), and fixed on the ceiling or wall through the chassis with 4×25 large flat-head self-tapping screws (required to be firmly fixed and safe).
