TIDA-00488 demonstrates an ultra-low power and a renewable method of wireless environmental sensing using daylight energy harvesting with a long backup battery life. This reference design uses our 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 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
