Arduino controls relay, connected to fans, and turns off and on based on temperature.

The task was to make the automatic inclusion of the heating system at a certain temperature (-10 degrees Celsius). I could use the arduino NANO controller, sensor ds18b20 in insulated body and the ...

After the temperature sensors detect deviance from the set point, or upon SMS instruction, the Freeduino will crank up the heat through a 5V relay attached to the home’s boiler.

Vous pouvez utiliser un Nano et une carte type relais Arduino bleu chinois :) équipé d'un shield SIM800L_EVB. (voir pièces jointes) Mesure la température du lieu d'emplacement du module à l'aide d'un ...

In this article, we propose a circuit to monitor the temperature and control a relay over the local WiFi.

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 ...

Temperature is controlled by an ON/OFF trigger-driven mechanical relay connected to the Arduino environment, which in turn generates an opportunely amplified signal to control the supply voltage of ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one ...
