|opis:||Nowadays, people in order to conveniently, will choose to buy bottled water in supermarket for a drink, this movement waste lot of plastic. Therefore, the government implemented a plastic recycling plan, and encourage people to compress the bottles before putting into the recycling bin, but many people still lazy, they just directly put the bottles into the recycling bin without compress. Those uncompressed bottles not just occupy a lot of space, and also increase the transportation cost of recycling. So that, we make this work to help people to compress the plastic bottles before throwing them into the recycling bin.
This device has two layers, the top layer is a compression device, and the bottom layer is a container for bottles. The principle of the compression part is to suck the air from the bottle through the air pump, under the atmospheric pressure difference, the bottle is flattened. In order to prevent the liquid in the bottle from being sucked into the air pump, a water storage bottle is placed to store the inhaled liquid to avoid damage to the air pump. And, at the bottom of the storage bottle, there is a pressure sensor for real-time monitoring water weight. We use Arduino planform be the monitoring system, when the water volume reaches 90% of the maximum storage capacity, the power of the air pump will be cut and then the red LED will be lighted to give a prompt.
