When the water freezes in winter, it is hard to intuitively judge if the ice is thick enough to support people in ice fishing, ice skating or other ice surface activities. Using modified river buoys, the design combines temperature sensors with a solar energy system to automatically monitor ice thickness, while provide intuitive instructions for people traversing the ice surface.
The main working principle of the product is as follows: temperature sensor 1 > 0℃ and temperature sensor 2 > 0℃ implies that it is all water (no lights); temperature sensor 1 < 0℃ and temperature sensor 2 > 0℃ implies that ice in thin (red light is on); temperature sensor 1 < 0℃ and temperature sensor 2 < 0℃ implies that ice is thick enough (green light on).
