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 video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...

The past month or so I’ve been playing with the Maxim DS1307 Real-Time-Clock and DS1621 Temperature Sensor ICs. I hooked them up to an Arduino Uno board with a Parallax Serial 16×2 Character LCD. I ...

A programmable temperature and process controller for use by the maker community has been designed to be Arduino-compatible. Called the SmartPID it can be programmed on a PC via the USB port using the ...

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

The first step is a thermistor, a conceptually simple device: resistance varies with temperature (seriously, how much more simple can a sensor get?). You can measure them by tapping the center of a ...

Environmental sensing technology has become increasingly vital in today’s world, where understanding and monitoring air quality and environmental conditions are crucial for sustainability and safety.

When life hands you a bunch of crummy capacitors, what do you do? Make a whole bunch of temperature sensors, apparently. The less-than-stellar caps in question came to [pyromaniac303] by way of one of ...

SST Sensing has partnered with Sparkfun to develop a simple to implement solution for single point liquid detection using infrared technology. The solution comprises an Optomax Digital liquid level ...
