Is the human body sensor easy to use? How to use it? Which do you buy between aqara green rice and Xiaomi

We all know about human body sensors , But netizens have different opinions about whether it is good or not , In the face of such questions , This article will talk about how to use human body sensors ？ What's the effect ？Aqara Green rice 、 Which is better to buy between Xiaomi ？

Now there are two main human sensors in Xiaomi ecosystem ： One is from the MI family ; One is green rice , But these two models have 4 Differences ： One is the price , The price of Xiaomi is 49 yuan , Green rice 74 yuan ; Second, green rice has a bracket , It can adjust a certain angle with the human body sensor , In fact, you can also buy this alone , Not expensive, about ten yuan ; Third, green rice has an illumination detection , The black part on the top is the illumination detection port ; Fourth, green rice supports HomeKit, however HomeKit It doesn't support Aqara Illuminance detection of human body sensor , So in the choice of these two products , You can choose according to your needs .

These two kinds of human body sensors can be used. If someone moves, it is to turn on the light or curtain , If there is no one to move, the trigger of the scene such as turning off the light or turning off the TV is the condition . Through this , It can be seen that at present, human body sensors are mainly linked with lighting equipment , Such as smart bulb or smart table lamp , And human body sensors can be used in these three places . 

The first one is the linkage light at the entrance hallway , Someone passed by and turned on the light , If no one moves for two minutes, the light will turn off automatically ; The second is under the computer desk , Let it help me judge , When I sit down, help me adjust the lights of my funny computer ; The third is on the door frame , When my home mode is triggered , Trigger once to turn on the light .

Of course, if you want to make good use of human sensors , First, understand his trigger angle , These two detectors are divided into horizontal ones 170°, The horizontal straight line can be detected longitudinally 7 A distance within meters . secondly , If it is higher than 2.1 There is a blind area at the bottom of the meter sensor , Some areas cannot be detected .

In fact, I think human sensors are much more important in smart home systems than voice triggering and physical button interaction , Of course   Compared with other sensors, the current human body sensors are relatively convenient , At the same time, it is also relatively flawed .
