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 ...

void loop() { delay(2000); // Wait for 2 seconds between measurements float humidity = dht.readHumidity(); // Read humidity value from sensor float temperatureC = dht.readTemperature(); // Read ...

We built this Arduino-based Digital Thermometer for temperature measurement applications. Thermometers have been useful for temperature measurement for a long time. A digital thermometer is an ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...
