Thermal Storage tank with PV and Thermal solar panels.

ADS1115+ESP-01 (1M) OTA updated based on https://goo.gl/AH8Y3w sketch adapted to my 30A CT and 6V transformer. ESP is powered from a separate 3.3V source.

My own device based on ESP8266. Sensor for temp, humm and pressure is BME280. Second sensor is MH-Z19 for CO2 concentration. Device located at office or home, Moscow, Russia.

Test feed running on a Wemos D1 mini (esp8266 variant) with a DHT22 for room temp/humidity data and a DS18b20 for the tank temperature. PWM control of tank lighting is handled locally. Light levels may follow at some point.

A weather station made from an Arduino / ESP8266 and a bunch of sensors. Based in Hebburn, Tyne and Wear. [STILL UNDER TESTING AND MAY GO OFFLINE]

Power meter in private house with photovoltaic plant, 3,75kW. Measurement and communication implemented by Arduino UNO and ESP-07 wifi module.

NodeMcu based weather station，by using BMP180 , DHT11 ,ESP8266 to implement the sensing and data uploading. This weather station was located in Hong Kong.
