Various Applications

Digital Weather Station with Arduino

The DHT11 sensor measures ambient temperature and humidity. These readings are displayed in real time on an LCD screen. In advanced versions, this data can be transmitted over the internet for remote monitoring.

Smart Greenhouse Monitoring System

A DHT11 sensor placed inside a greenhouse continuously monitors environmental conditions. When humidity falls below a set threshold, an automatic irrigation system is activated. Similarly, when temperature rises excessively, ventilation fans can be triggered.

Humidity-Controlled Fan System

A simple control system can be designed to turn a fan on or off based on humidity data from the DHT11 sensor. This system can be used to automate ventilation needs in small enclosed spaces.
