Description

Energy Harvesting Envi Sensor Breakout v1.0 is a ultra-low power and renewable method of Wireless Environment Sensing using daylight energy harvesting with extremely long battery backup. 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
