Temperature and Humidity Monitor

In this instructable Im going to show you how to make your own temperature and humidity monitor for your living room. The device also features WiFi capabilities, for the purpose of logging the data on a remote server (e.g. a Raspberry Pi) and accessing it later through a simple web interface.
The main parts of the device are an ESP8266 microcontroller, a DHT11 temperature and humidity sensor and a 16x4 character LCD. The project is fully open source, so feel free to download the schematic, board layout and design files for the enclosure and make any changes you like.”
