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 ...

You will need a pull-up resistor of about 5 KOhm between the 1-Wire data line and your 5V power. If you are using the DS18B20, ground pins 1 and 3. The centre pin is the data line '1-wire'. This ...

[George Dewar] and his wife live in a typical 1940’s house in New Zealand , which in case you didn’t know, have a little insulation in the ceiling… and nowhere else. Like most, they put up with the ...

In this project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...

This water level and temperature monitoring system uses contact or non-contact water level sensors along with a probe-type temperature sensor. A digital display provides continuous, real-time ...

[Kerry Wong] comes across the coolest hardware, and always manages to do something interesting with it. His widget du jour is an old demo board for a digital RF attenuator chip, which can pad a signal ...

Thermistor is a semiconductor device made of materials whose resistance varies as a function of temperature. A thermistor can be used to compensate for temperature variation in other components of an ...
