HARVESTREE
Description
The Harvestree connected measurement modules allow to measure up to four different physical quantities (temperature, pressure, vibration...) in a completely autonomous way, without batteries nor wires. The Harvestree module is self-powered thanks to the thermal energy present in its environment. This energy is used to power sensors, radio emission (LoRa) and energy storage. The Harvestree module can thus transmit 4 measurements every 5 minutes with a temperature difference of only 10°C!
