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 ...
Now you can build your own room temperature monitor using an Arduino board. The circuit is a combination of an Arduino UNO board, LM35 temperature sensor, and a 16×2 Hitachi compatible LCD. It will ...
