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 the cloud. It maintains the energy balance by performing power management with zero human intervention.

  • The SOTB MCU will be in software-standby (or off) mode most of the time.
  • During its low-power mode, the Energy Harvesting Capability charges the rechargeable battery from a solar panel, checking its voltage level periodically.
  • Performs power management by maintaining the energy balance between power generation and power consumption.
  • When there is enough power stored, the MCU wakes and communicates with the temperature and humidity sensors and gathers the data, then sent out via communication.
  • Displays the temperature and relative humidity data on its LCD panel.
  • Smart agriculture sector
  • Smart metering
  • Remote sensing

RE Solution: Battery Maintenance-Free LoraWan® Sensor

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.
