Arduino-Weather-Monitor This project uses an Arduino, a DHT11 temperature and humidity sensor, and a 16x2 LCD display to monitor and display environmental conditions.

This setup features an Arduino Uno CH340G clone connected to a DHT11 temperature and humidity sensor and a USB-to-Serial adapter (CP2102 module). The DHT11 sensor is connected to digital pin 2 for ...

A DHT11 monitors the temperature and humidity. A charge circuit and lithium battery provide power. Finally, the watch displays the date, time, and other data with an LCD from a Nokia 5110.
