Low Power Wireless PIR Motion Detector Reference Design Enabling 10 Year Coin Cell Battery Life
Description
The TIDA-00489 TI Design uses nano-power operational amplifiers: comparators: and the SimpleLink ultra-low power sub-1GHz wireless microcontroller (MCU) platform to demonstrate a low power wireless motion 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 motion detection or lighting control through occupancy detection. The PIR sensor has sensitivity of up to 30-feet with standby current of 1.65-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 single CR2032 Coin CellLow Standby Current of 1.65uA (PIR sensor remains active in Standby)Ultra-Low Active State Current Due to Low Active Processor and Radio Transmit Currents (1.12mA for 104.1ms)Interrupt Driven Sub-1GHz Wireless Communication of Motion for Increased Power SavingsMotion Sensitivity up to 30ft
