detect temprature and humidity by dht11,ethanol gas by mq3 sensor

Scheme to use drier Outside air to minimize basement dehumidifier run time

Node MCU 1.0 get data from DHT11 and send it to sever

Via SmartThings

measurement temperature and humidity using dht11 sensor

Temp and Humidity

Weather station in Lübeck, Germany.

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]

Weather in Munich

Gives temperature, humidity, pH value, water level, water temperature, soil moisture level data

Temperature sensor DS18B20 on Feather Huzzah ESP-12S

The water temperature in water levels of the storage tank for house heating.

Arduino Mega 2560 with ethernet shield, 16x2 I2C LCD, RTC DS3231, SD card datalogger, two DHT22 sensors and two DS18B20 sensors
