Low power wireless PIR motion detector reference design enabling sensor-to-cloud networks

The TIDA-01476 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.

Features

• 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
