Reference Design to Extend Coin Cell Battery Run Time in Wireless Ultrasonic Gas Leak Detector
TIDA-01236
Overview
This reference design demonstrates a low-power wireless sensor which detects gas leaks by analyzing the ultrasonic spectrum for particular signatures. The system is designed to operate from a single Li-Primary coin cell and communicate wirelessly to a base station, which removes all requirements for wiring and enables easy installation. The design incorporates an ultra-low-power battery fuel gauge to accurately predict battery health and provide advance notice of upcoming end-of-life for scheduled battery replacement.
Features
- Accurate li-primary battery gauging enables extended lifetime and predictable maintenance
- Uses multiple power domains to optimize system current consumption
- System diagnostics available for precision power evaluation during development
- Over three years of operation on coin cell battery ehen sensing every 30 seconds
- Leak detection independent of gas type; does not require concentration of gas to contact sensor
Industrial
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
