Temperature and Humidity Sensor Module (DHT11/DHT22) Project

The Temperature and Humidity Sensor Module project showcases how to use an Arduino Mega with DHT11 or DHT22 sensors to monitor environmental conditions. These sensors provide accurate temperature and humidity readings, making them ideal for applications requiring climate monitoring or environmental control.

Components Needed

• Arduino Mega
• DHT11 or DHT22 Sensor
• Jumper Wires
• Breadboard
• Power Supply
