This project collects temperature and humidity data using a DHT22 sensor connected to an Arduino. Data is sent via a Python bridge to a Flask backend, which validates and stores it in MongoDB. The ...

Real-time environmental monitoring is increasingly important in agriculture, industrial automation, smart homes, and healthcare. The real-time data monitoring ...

In this project, a Temperature Monitoring System is developed using Arduino and a temperature sensor (such as LM35 or TMP36). The system is capable of reading the temperature from the sensor and ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...
