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.

Features

  • 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 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 & humidity sensors and gathers the data, then sent out via communication.
  • Displays the temperature and relative humidity data on its LCD panel.

Applications

  • Smart Agriculture Sector
  • Smart Metering
  • Remote Sensing
