Description

The TIDA-00759 TI Design uses nano-power operational amplifiers, comparators, and the SimpleLink™ ultra-low power 2.4GHz 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 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 single CR2032 Coin Cell
  • Low 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 Savings
  • Motion Sensitivity up to 30ft
