The RE family is a new product that uses the Silicon on Thin Buried Oxide process. In addition to its low power consumption performance, it has an integrated power supply circuit (EHC), which is necessary for energy harvesting systems.
Ultra-Low-Power LoRaWAN® Sensor uses Renesas RE Family’s energy harvesting functionality to create an ultra-low power, highly efficient, maintenance-free solution. The system is capable of measuring temperature, relative humidity etc. and sending this information via Sub-GHz technology(LoRa®) to cloud. It maintains the energy balance by performing power management with zero human intervention.
