For those who love plants, is a sadness leave home or forget to feed them and give them the water they need, however, for this serves Plant Friends: this is a moisture sensor on earth that sends us an alert through a email or text message when they need to be watered.
The mechanism consists of two subsystems: the wireless, which is composed of moisture sensors and a base which processes the collected data; it is powered by four AA batteries, which lasts about 4.5 months; and a mobile app that lets be connected to the database via the Internet to monitor information in real time.
The Dino, Bunny and Robot characters are made of bamboo, and include a compartment for these sensors that operate by a system similar than Arduino, called Monteino, developed by LowPowerLab. In addition to wireless transmitters, each character has led lighting covered by a layer of translucent acrylic that indicates when the humidity is low or the battery is about to run out.
