One Arduino get the datas from two SolarMax MT-Serie converter. Pmax=32KW DC.

Get Real time data of temperature,humidity and soil moisture.

SRHPE 150 litre Solar Ray Geyser Analysis. 19 direct coupled vacuum tubes 1.8m long x 58mm dia. Panel is facing North East set up at 35º to horizontal on top of flat roof. LDR estimates light intensity by Lux = 500/(Rldr)^1.3

Weather Station positioned under a outside south faceing roof. Temps and Pressures from BMP180, Humidity from DHT22, monitored by a ESP8266.

Arduino Pro Mini (3.3 V, 8 MHz) measuring outside temperature and humidity using a DHT21. Powered by 3 AA eneloops using (only) the on-board voltage regulator. Battery voltage is measured by internal ADC. Wifi connected by esp8266
