Measuring temperature and humidity featuring LC display and webserver upload using Arduino with Ethernet shield, LCD and realtime clock

This project consists of two parts: an Arduino-based module to measure temperature and humidity and sending these data to a webserver, plus a simple server-side php webpage to display and archive the measurements.

Components used: The Lcd-Meter project uses an Arduino UNO or similar, together with an Ethernet shield (W5100 type), a DHT22 temperature/humidity sensor, a DS3231 realtime clock module, and a 16x2 LCD module. The latter two are connected by I2C, while the Ethernet module uses SPI and the DHT22 sensor is connected via 1-wire protocol.”
