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 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 ...

The DS18B20 is a digital temperature sensor from Dallas Semiconductors, which is now part of Maxim (https://datasheets.maximintegrated.com/en/ds/DS18B20.pdf). The ...

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 ...

The Raspberry Pi Pico is the new kid on the microcontroller block. How does it compare to the long-established Arduino Nano?

Arduino debuted its newest product, a single-board computer called the Uno Q, in conjunction with today’s acquisition ...

Temperature sensing plays a pivotal role in controlling and monitoring industrial, chemical, and biomedical systems. There are some complex internal space structures such as porous and zigzag in ...
