Uses D1 Mini with configuration stored in RTC memory. Data updates every 10 minutes here and on https://aprs.fi/W4KRL-13. The device is housed in an AcuRite Instrument Shield. Near-term (12-hour) forecast uses the Zambretti algorithm: w4krl.com/zambretti

* Field 1-3: Solar panel 50x50mm (2V, 70mA), D1 Mini Pro in DeepSleep (4min) and ESP-Now. Sending to ESP32 (gateway) which logs to ThingSpeak. * Field 4-8: Solar panel 100x60mm (6V, 1W), D1 Mini in DeepSleep (5min) and WiFi logging to ThingSpeak.

Measures the relationship between light intensity and solar panel power output. Panel is 80 x 55 mm rated at 6 V 100 mA. An INA219 measures current, voltage, and power output. A TP4056 controls the charge of a 600 mAh cell. Reports every 5 minutes.

Monitored Solar Voltage, Current, Temperature and Humidity

WeMos D1 Mini Pro based on project: https://www.opengreenenergy.com/post/solar-powered-wifi-weather-station-v2-0 and https://github.com/3KUdelta/Solar_WiFi_Weather_Station

Remote monitoring of solar system parameters and battery bank status with automated auxiliary battery charger control.

Simple weather station by using Ti HDC1080 temperature & RH sensor and ESP8266 module configured in deep sleep mode. The whole unit is powered by 1000mAH lipo battery and a small solor panel (below 1W).

This is a test channel created by Sarath SM to test the TestSM IoT channel to monitor the Solar Harvesting Unit.
