Measurements of Temperature and Humidity Using DHT11 Sensor

Measure Temperature and Humidity using NodeMcu

from NODEMCU

This weather station was designed by Karl Berger. This weather station was built by Turner Bumbary and he hopes to use the weather data to forecast weather in developing countries.

Data from DHT22 sensor

ESP8266 running NodeMCU with a DHT11 to report humidity and a BMP180 to report pressure and temperature. The Sensor also reports battery voltage which is 2xAA batteries. Photo: http://imgur.com/hDpeNxj

Freezer-to-Frigidaire, ESP8266 powered freezer cell periodically shut down to stay within typical refrigerator temperature range (e.g. 2 to 5°C) A DHT22 inside the freezer is polled and a 5V relay and a cascaded BIG 220v SSR are switched accordingly.
