Chinese manufacturing giant, Xiaomi, is currently crowdfunding a smart trash can which automatically opens when a significantly large object (like a human body) is close to it and closes back when the object moves away. This prevents flies and mosquitoes from hovering about the trash can. The sensing distance is 35 cm thus you have to be quite close before the Xiaomi smart trash can opens up. Note that the cover of this trash bin can be locked so that babies can not easily access this dirts inside. The crowdfunding price is 199 Yuan ($30) but as usual, this price might be higher when this product eventually hits the market.
In addition, the trash can also has an automatic sealing and bag changing function, thus you can pack the garbage without having your hands-on and automatically seal the garbage bag, which is convenient. The capacity is 15.5L and it comes with a special non-breaking garbage bag.
It is not necessary to change the bag manually in one month in an average environmental setting. In terms of battery life, the Xiaomi smart trash can has a large-capacity battery and can be used for about 35 days under normal conditions. In addition, this smart trash can also has a built-in LED strips, which have three modes: fade, steady and breath.
