Overview

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.

Features

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
