ESP-WROOM-32 on a selfmade PCB-layout with an BME280 sensor. Powered by an 1W 6V Solarcell and a 2000mAh LiPo Battery. The device is up for 1300ms and sleeps 10 minutes. The current while sleeping is about 11µA and at uptime about 100mA.

My hybrid solar home project.

Raw values taken from Solar Analysis on channel 123452. Temperature and humidity are measured under a solar geyser on the roof.
