The fan and the plug were later added using photoshop. The diagram consists of an arduino,a relay, an lm35 sensor, an AC fan, and a plug. The temperature controlled fan circuit is very simple. The ...

Setup Function: setup(): Initializes serial communication at 9600 baud rate. Sets the LED pin (led) as an output. Sets the LM35 pin (LM) as an input. Loop Function: loop(): Reads the analog value from ...

Arduino Board: Serves as the central control unit to process sensor data. DHT11 Sensor: A compact and affordable sensor for measuring temperature (in Celsius) and humidity (as a percentage).

DS18b20 Temperature Sensor: In-Depth. The DS18B20 is a digital thermometer that can provide 9-bit to 12-bit resolution and can measure temperatures from -55°C to +125°C. This is a unique chip designed ...

This isn’t about connecting a temperature sensor in your Arduino. ... The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

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 ...

This temperature and humidity sensor gives more accurate readings as compared to the popular DHT11 sensor. With this sensor, you can easily program to get humidity in %, and temperature in °C and °F ...
