This project showcases the use of an Arduino and a DHT11 sensor for real-time IoT applications. It includes various example codes for testing the sensor, connecting to the Blynk IoT platform, and ...

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

[Edward], creator of the Cave Pearl project, an underwater data logger, needed a way to measure temperature with a microcontroller. Normally, this problem is most easily solved by throwing a ...

The hardware setup shown below includes the Arduino Uno R4, a DHT11 sensor, and the built-in Wi-Fi for email alerts. The DHT11 is connected with VCC to 5V, GND to ground, and the data pin to Digital ...

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 ...

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 ...

In our daily lives, we use thermometers on various occasions and for various purposes, from medical needs to repair and diagnostic purposes. As you know there are different types of thermometers, and ...
