Description

The TIDA-00756 TI Design uses nano-power operational amplifiers, comparators, system timers, temperature sensors, and the SimpleLink™ ultra-low power 2.4-GHz wireless microcontroller (MCU) platform to demonstrate an ultra-low power carbon monoxide detector implementation. These technologies lead to an extremely long battery life, over 10 years with a standard CR2032 lithium ion coin cell battery, which could be used for applications including gas detection or air quality monitoring. The carbon monoxide detector has sensitivity up to 1000 ppm with a standby current of 1.07-µA. The design guide includes techniques for system design, detailed test results, and information to get the design up and running quickly.

Features
  • Use of nano-power analog ultra-low-power design resulting in 10-year battery life from single CR2032 coin cell
  • Carbon monoxide gas sensor and analog logic always powered on to enable continuous monitoring and fast response times
  • Bluetooth® Low Energy (BL) wireless connectivity reduces installation costs and allows multiple sensors to communicate with single host
  • Self-check and end-of-life monitoring recognizes malfunctioning gas sensor and reports status every five minutes (configurable)
  • Carbon monoxide gas detection range of 0 to 1000 ppm with ±15% accuracy
