Advantages of microwave radar sensors over voice-activated sensors - [Twllink]
The microwave radar sensor is based on the Doppler principle to sense whether the object moves in a noncontact manner to achieve the relevant switching operation. During the period after the induction light is turned on, if someone is within the detection range, the switch will continue to be turned on until the person leaves and delays the time, and the power is turned off automatically.
The voiceactivated sensor switch has a similar receiver that accepts external sounds. After amplification, the relay or thyristor is pushed.After a delay circuit is turned off, the circuit is turned off to operate the switch.However, the microwave radar sensor has evolved intoa steerable, energy-saving, and intelligent sensor switch in response to the development of the times.
|Microwave radar sensor|| infrared sensor|
|Longer service life and less prone to outside interference.||It is easily interfered by external factors and has a low service life.|
|The installation is concealed and the luminaire can be controlled directly in the lampshade.||It is exposed to the outside world and is easily eroded and destroyed by the outside world.|
|High sensitivity, able to penetrate glass and thin wood.||Low sensitivity, unable to penetrate glass and wood.|
|Not affected by the environment, temperature, sound, dust, etc.||It is susceptible to external environment, dust, sound, and temperature.|
|Wide range of applications, parking areas, toilets and other monitoring sites.||Only suitable for smaller range spaces.|
|Strong anti-radio interference capability, weak anti-interference ability||No moving object automatically turns off after the delay time|
