This is an IoT project using ESP32 and DHT22 to monitor real-time temperature and humidity. The data is visualized on the Arduino IoT Cloud dashboard. Assemble the circuit following the layout shown ...
void loop() { delay(2000); // Wait for 2 seconds between measurements float humidity = dht.readHumidity(); // Read humidity value from sensor float temperatureC = dht.readTemperature(); // Read ...
