Humidity & Temp Sensor Node for Star Networks Enabling 10+ Year Coin Cell Battery Life Ref Design
Description
This reference design uses our 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 of over 10 years with a standard CR2032 lithium-ion coin-cell battery. The 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 cellConfigurable system wakeup intervalLow 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
