Sonic, infrared, radar three kinds of T8 induction lamp comparison which is better

Sound induction: the oldest and most traditional induction technology in the lighting industry, mainly by sensing the sound decibel, the main decibel boundaries will be all lit up, it is easier to be affected by the environmental sound factors, the phenomenon of mis-sensing.

Infrared sensing: infrared sensing, also known as the human body sensing, the need for exposed Fennel sensing probe to sense the human body temperature, the normal sensing distance is about 2-5 meters, when the ambient temperature and the human body temperature is similar, for example, in summer, the infrared sensing on the sensing distance is relatively short reaction slow people walk through the light, or even no sensing.

Radar sensing: radar sensing is the use of Doppler sensing technology, 360 ° transmit and receive sensing signals, in the sense of the range (6-8 meters) there are obvious moving objects, will trigger the induction, the light has a slightly bright or all out to change to a fully bright state. Radar induction sensitivity, from trigger to response is only 0.1-1 seconds. And continuous sensing continues to light up, only when needed to light up, more than intelligent and more energy-saving. At present, the radar sensor lamp is also the best choice to replace the infrared human body sensors or voice-activated sensors, so the radar sensor lamp is the best choice for garage lighting
