Smart home has become the interest point of many young people today, and it only takes a few dozen yuan to bring a lot of convenience to life.  Today, Xiaomi Youpin crowdfunding put on the shelves a product called Xiaoda induction water saver, which can turn your traditional faucet into a smart sensor model. Its crowdfunding price is only 79 yuan, and the future listing price is 149 yuan, which is almost half price.  It is understood that Xiaoda induction water saver uses infrared induction water outlet, two sets of sensing areas, two water outlet modes, 0.25 seconds fast sensing, convenient water outlet. Users do not need to switch the faucet on and off repeatedly, reach close to the water flow, and avoid transferring bacterial stains to the faucet.  It adopts innovative technology design, adopts XD2.0 innovative algorithm and pulse interval sampling to optimize infrared sensing, which significantly reduces product energy consumption and ensures the infrared sensing sensitivity of the product used in complex environments, as well as the sensing distance.  When the sensor enters the bottom sensing area within 0-10cm, water starts to come out. When the sensor leaves, water stops coming out. If the sensor stays in the bottom sensing area all the time, the water will automatically stop coming out after 20 seconds to protect it, meeting the needs of daily cleaning.  When the sensor enters the side sensing area within 0-5cm, water starts to come out. The water outlet time lasts for 3 minutes. If the sensor enters the side sensing area again during the water outlet process, the water can be stopped. It is a good choice for water storage.  It also uses air injection technology to increase the proportion of air in the water outlet process, so that the water is gentle and delicate and has initializing force, while reducing the unused water outlet time, smaller aperture solenoid valve cavity and fine filter screen, so that the air injection is larger, water saving is soft, dynamic water saving 35%. Reach the first-class water efficiency level.  In terms of battery life, Xiaoda induction water saver is equipped with Type-C charging port, it takes 3 hours to fully charge, and can last up to 6 months. Compared with the previous generation of products, the solenoid valve driver is integrated into the chip, reducing the loss of peripheral drive circuit and higher battery life efficiency. When the power is insufficient, the automatic light will remind.
