The company continues to make our lives even more comfortable and better! This time we will talk about the sensor attachment on

faucet from Xiaomi, which will not only make it easierlife, but will also save several cubic meters of water! The water supply is controlled using infrared sensors. The device has high autonomy and overflow protection. I think many are interested in the new product, let's proceed to a detailed review of the Xiaomi Smartda Induction Home Water Sensor.

Xiaomi Touch Sensor Nozzle

I'll say right away — this attachment is reallyIt’s an extremely convenient and useful thing to have around the house, although you need to get used to it. You don’t need to constantly turn on the water supply; just bring your hands to the nozzle and the sensors activate the pressure. The response speed is only 0.25 seconds. During operation, aeration occurs — saturation of water with oxygen. This makes it softer and reduces consumption.


Consider the principle of operation of the nozzle. It is equipped with two sensors at once, which makes it possible to diversify application scenarios.

Bottom sensor

It is responsible for temporary water supply and worksas follows: they raised their hands — the pressure is activated, removed, the jet stops. If your hands are in the sensor area for more than 20 seconds, the water supply will be automatically stopped. The sensor reacts within10 cm.

Side sensor

Response area: at a distance of no more5 cm. We spent near the sensor — constant water supply was activated (it runs for 3 minutes and turns off automatically), ran it again — the nozzle has stopped working.


The Xiaomi faucet attachment has excellent autonomy. The built-in battery allows the device to operate on a single charge for about6 months(depends on frequency of use). Charging occurs via a standard micro USB connector.

Personal impressions

Touch faucet attachment from Xiaomi in useabout 2 weeks, and I am satisfied with her work. The sensors respond clearly and without delay.
