This design is powered by photovoltaic (PV) panels and batteries, and it monitors the temperature, humidity, ambient illuminance, and trash level inside a waste bin. It detects human proximity and offers buttonless control. Leveraging the LTE-M/NB-IoT platform, it can efficiently send out maintenance messages when the waste bin is full, or warning messages in the event of dangerous conditions.

System Benefits​:

  • The new RL78 MCU generation provides further refined low-power performance and enhanced capacitive sensing unit (CTSU2L). It supports a touchless button system lessening concerns over contaminated surfaces.
  • The cellular module delivers the most mature and field-proven LTE-M/NB-IoT protocol stack.
  • High-performance and quality sensors detect multiple environmental data.
  • Low-power design and high-performance power system support green energy.
