The DS18B20 is a digital temperature sensor that comes in two versions: a small TO-92 package, and a waterproof variant often encased in a metal tube with a long cable. Both provide digital ...

Last time, we used a light sensor to measure ambient brightness and even created a control system that turns on an LED when ...

With the compliments of the Elektor Editorial and Labs teams, here is a 'fresh' article presented free of charge to all Elektor e-zine subscribers. This time we have author Werner Möhrle discuss his ...

The LM35 is a precision integrated-circuit temperature sensor (PTAT; proportional to absolute temperature) manufactured by Texas Instruments (https://www.ti.com ...

The temperature sensor detects the surrounding temperature. It generates an analog voltage proportional to the temperature. Arduino reads this voltage through Analog Pin A0. The analog value is ...

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 ...

The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...

Last time, we used a light sensor to measure the ambient brightness with an Arduino. When the light hitting the light sensor ...
