Join a free Arduino and Mouser webinar on taking Arduino Pro from prototype to production in industrial automation.

Now you can build your own room temperature monitor using an Arduino board. The circuit is a combination of an Arduino UNO board, LM35 temperature sensor, and a 16×2 Hitachi compatible LCD. It will ...

Working Principle: The TMP36 temperature sensor gives analog output proportional to the temperature. The Arduino reads this analog voltage from the sensor using the analogRead () function and converts ...

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.

This project is an automated kitchen safety and ventilation system built using an Arduino UNO R3, a DHT22 temperature & humidity sensor, an MQ-2 gas/smoke sensor, and a relay module connected to an AC ...

Flexible, low-cost temperature- and pressure-sensing devices are of profound importance in satisfying the urgent requirements for many advanced artificial ...
