working principle: switch "on ", the light will always light up. switch "auto", human motion sensor mode, only turns on in the dark environment, the light will illuminate when you get within 2 meters of it and it will go out 20-30 seconds after you walk beyond its sensing range. Spe...
Working principle: vibration sensor Sensor type: 2.4GHz to 5.8GHz radar sensor Material: mixture Specification: 1. Independent of temperature, humidity, airflow, dust, noise, light and dark, anti-interference, etc. 2. The transceiver module is a field-shaped signal with a wide coverage ...
The first motion sensor was invented in the year 1950 by Samuel Bango named as a burglar alarm. He applied the basics of a radar to ultrasonic waves – a frequency to notice fire or robber and that which human beings cannot listen to. The Samuel motion sensor is based on the principle o...
The purpose of this chapter is to describe the working principle of the micro electro mechanical systems (MEMS) devices used in motion sensors, and to consider their level of sophistication and future evolution. The integration of a multi-parameter sensor in a single unit can increase the ...
