The two modules are installed on the same building, one on the East side and one on the West side. Location: Athens, Greece. Hardware: ESP8266 running on nodeMCU firmware with DS18D20 sensor.
Weather Station positioned top of cellar near the roof. Temps and Pressures from BMP180, Humidity from DHT22, lux estimated form LDR all monitored by a ESP8266.
One Arduino get the datas from two SolarMax MT-Serie converter. Pmax=32KW DC.
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.
