We will first interface the LM35 sensor with Arduino UNO to measure the surrounding temperature and relay to control the fan. We will then upload the conditional code in Arduino and check the output.

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

The code continuously reads the temperature from the LM35 sensor and adjusts the LED's behavior accordingly. If the temperature is below 30.0 degrees Celsius, the LED blinks with a 250 milliseconds on ...

The DHT22 temperature and humidity sensor is a versatile and cost-effective sensor ... we can connect all the required wires to Arduino and write the code to get all the data out from the sensor. The ...

This isn’t about connecting a temperature sensor in your Arduino. This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno ...

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, ...

You can use the DHT22 (or AM2302) humidity/temperature sensor and the Arduino UNO board to read data and print it ... DHT library that is very simple to use and if you follow the code line by line ...

Presented here is a humidity and temperature monitoring using Arduino. In this article, humidity and temperature information from DHT-11 sensor is analysed graphically on ThingSpeak platform using ...
