TIDA-01518 Reference Design

Texas Instruments

Low-Power Flood/Freeze Detector Reference Design With Sub-1 GHz and 10-Year Coin Cell Battery Life


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 10-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
  • Water Leak Detector
