Description

The TIDA-00488 TI Design demonstrates an ultra-low power and a renewable method of wireless environmental sensing using daylight energy harvesting with an extremely long backup battery life. This design uses Texas Instruments’ ultra-low power harvester power management; SimpleLink™ ultra-low power sub-1 GHz wireless microcontroller (MCU) platform; and ambient light, humidity, and temperature sensing technologies to achieve continuous monitoring while the energy harvesting circuit is active and interrupt monitoring when running from the backup battery

Features
  • Runs entirely from solar energy when lux level is sufficient (continuous mode)
  • Supports interrupt mode triggered by indoor LUX levels
  • Long backup battery life (up to 10 years) in interrupt mode
  • Senses natural ambient light coming into a building to precisely control the building's lighting systems
  • Monitors temperature and relative humidity in addition to ambient light
