Aqara vibration sensor

Hello friends

Today I want to talk about a new gadget for the system of smart home from Xiaomi – A vibration sensor from the brand Aqara, known to every builder of smart home.

I’ll start as always with the box. It is unusually large for such devices. Framed in the traditions of the genre, except that the list of parameters of the Aqara vibration sensor moved from the back side of the box to one of the ends. The sensor works on the ZigBee protocol, has an autonomous power supply on the element CR2032 and size 36 * 36 * 9 mm.

There is a lot of empty space in such a big box, I don’t know why they did it. But a dozen of these sensors would be easily entered into it.

In addition to the sensor-included a spare sticker double-sided tape and instruction, and multilingual-is present even in the Russian language.

The appearance of the sensor has a traditional for Aqara gadgets, square shape and appearance. Moreover, it is exactly the same as the temperature, humidity and pressure sensor, excluding markings and no openings to measure the relative humidity.

On the frontal surface there is a marking in the form of two wavy lines, and a blue led.
At the top end of the sensor is the pairing button with the gateway.

Behind-a cover, with already pasted bilateral tape under which there is a 3 volt battery CR2032.


The sensor plugs into the Aqara application directly or through the gateway plug-in. Connection Wizard Standard-Select the desired sensor from the list, press and hold the sensor button to 3 flashes of diode and select the room in which the sensor will be.

The sensor plug-in has a standard two windows-in one of them the list of scenarios in which the sensor is involved, in another-a log of positives. Everything else is on the menu

From the exclusive-in the menu of the sensor there is statistics on the curve of vibration, apparently in the context of the day and the week, the data is not updated yet, and their meaning is incomprehensible to me. There is also a configurable level of sensitivity, the default is medium. If you need to change-it is better to select it experimentally depending on the tasks, then after selecting the level, you need to press the button on the sensor and get a voice confirmation from the gateway.


The sensor, of course, can only be used as a scenario condition. It offers three exposure options — vibration, throw, and tilt detection. In the logs, these actions are displayed, respectively, as object is touched, object drops, and Tilt detected. Experimentally I have established that the first action-detection of vibration, can not be more often than once in a minute, the second and third-as the action is committed.

What do all these actions mean?

The event is a vibration detection, generated as I said no more times in 1 minute, for it is necessary, as the name implies, the impact of vibration. For example, the sensor is in the closet, when closed the doors or window, it caused vibration. Or it is on some object which has been shifted, on a safe a door which has opened and closed, on a chair on which have sat and so on.

The throw event is generated when a similar fall or throw is in motion. Use cases-to track the fall of some items, or for example, sharp closures of caps.

Tilt, or rather say offset, is the action that will be generated when the sensor is docked on a door or window and that will move. Unlike the open sensor — which generates statuses — open or closed, the vibration sensor generates precisely the movement of the window or door, can be useful in cases where the door in principle is not closed, or is sliding or rotating.

The use of such a sensor-I think a lot, and now you can decide whether you need it or not, and for what, personally for yourself, I still see two cases-a movement of doors that are not always closed, and working surface vibration when opening/closing the door The safe is for the illumination automation.
