Low-Power PIR Motion Detector With Bluetooth Smart & 10-Year Coin Cell Battery Life Reference Design
Description
This reference design uses nano-power operational amplifiers: comparators and the SimpleLink™ ultra-low power 2.4-GHz wireless microcontroller (MCU) platform to demonstrate a low-power wireless motion detector implementation. These technologies lead to an extremely long battery life of over 10 years with a standard CR2032 lithium-ion coin-cell battery which could be used for applications including motion detection or lighting control through occupancy detection. The PIR sensor has sensitivity of up to 30 feet with a shutdown current of 1.63 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 for ultra-low power design resulting in 10-year battery life from a single CR2032 Coin CellLow shutdown current of 1.63 uA (PIR sensor remains active in shutdown)Ultra-low active state current due to low active processor and radio transmit currents (1.57 mA for 56.66 ms)Interrupt-driven Bluetooth® smart wireless communication of motion for increased power savingsMotion sensitivity up to 30 feet
