TIDA-00758

Interrupt-based environmental sensor node with ambient light for Sub-1 GHz networks reference design

TIDA-00758

Design files

Overview

This reference design demonstrates a low-power method of wireless environmental sensing enabling up to 10 years of coin-cell battery life.  The ambient-light sensor enables lighting control for applications  such as automatic window blinds or daylight harvesting. This design uses our SimpleLink™ ultra-low power sub-1 GHz wireless microcontroller (MCU) platform and ambient light, humidity and temperature sensing technologies to achieve interrupt-based sensor monitoring when running from the backup battery.

Features
  • Supports interrupt mode radio wake-up triggered by indoor LUX levels
  • Long backup battery life (up to 10 years)
  • Monitors ambient light to precisely control a building lighting system
  • Senses ambient humidity and temperature to control the building HVAC system
