Alex Lynn

This reference design uses Texas Instruments low-power consumption digital dual temperature and humidity sensors and the SimpleLink ultra-low power Sub-1 GHz wireless microcontroller (MCU) platform to demonstrate a flood and freeze detector with extremely long battery life and no wiring required.


  • Ultra-low-power design resulting in ten year battery life from single CR2032 coin cell.
  • Conductive water sensing always powered on to enable continuous monitoring.
  • Designed for SimpleLink Sub-1 GH CC1310 wireless microcontroller (MCU) LaunchPad development kit (LAUNCHXL-CC1310).
  • Ability to take high-resolution temperature and humidity data.
  • Simple design that leads to lower cost.
