Description
This TI Design uses Texas Instruments nano-power system timer, SimpleLink™ ultra-low power wireless microcontroller (MCU) platform, and humidity sensing technologies to demonstrate an ultra-low power method to duty-cycle sensor end nodes. These technologies lead to an extremely long battery life: over 10 years with a standard CR2032 lithium ion coin cell battery. The TI Design includes techniques for system design, detailed test results, and information to get the design up and running quickly.
Features
- Use of Nano-Power System Timer to Duty-Cycle the System Results in 10+ Year Battery Life from CR2032 Coin Cell
- Configurable System Wakeup Interval
- Extremely Low Off-State Current (183 nA for 59.97 seconds)
- Ultra Low On-State Current Due to Low Active Processor and Radio Transmit Currents (4.04 mA for 30 ms)
- ±2% Relative Humidity Accuracy
- ±0.2°C Temperature Accuracy
