Low Power Wireless PIR Motion Detector Reference Design Enabling Sensor-to-Cloud Networks


Design files


This reference design demonstrates how to create an industrial sensor-to-cloud end node capable of connecting to an IoT network gateway and cloud data provider. This design uses Texas Instruments’ nano-power operational amplifiers, comparators, and the SimpleLink™ ultra-low-power Sub-1 GHz wireless microcontroller (MCU) platform to demonstrate an ultra-low-power sensor-to-cloud motion detector, leading to extremely long battery life and no required wiring.

  • Large network-to-cloud connectivity enabling long range, up to 1km (line of sight)
  • IEEE 802.15.4e/g standards-based sub-1 GHz solution with TI 15.4-stack
  • Use of nano-power analog for ultra-low-power design, resulting in 10-year battery life from single CR2032 coin cell
  • Low standby current of 1.65 μA (PIR sensor remains active in standby)
  • Interrupt driven sub-1 GHz wireless communication of motion for increased power savings
  • Motion sensitivity up to 30 feet

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
