Changes in our society, such as with home health and elderly care, and refrigeration, make it important to know when you have lost power. Many times when the power goes down, Wi-Fi loses connectivity because of a breakdown in infrastructure within the home. Combining NB-IoT/Cat-M1 with rechargeable batteries can solve this issue and notify home/business owners of a main power loss.

System Benefits

  • Low-power MCU with integrated ADC
  • NB-IoT/Cat-M1/BLE certified module
  • Light sensor to support filter exchange detection
  • Opto-isolator for zero-cross timing and monitoring external signals
