TIDA-00374
可讓鈕釦電池壽命長達 10 年以上且適用於星狀網路的濕度及溫度感測器節點參考設計
TIDA-00374
概覽
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.
特點
- 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
- 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
