Although this circuit connects the DS18S20 1-Wire temperature sensor to a Cypress CY8C26443 PSoC microcontroller, designers can easily adapt it to connect other 1-Wire devices to any microprocessor.

The AD590 is a two-terminal sensor with current proportional to temperature in degrees Kelvin. The proportionality is factory trimmed to be 1 µA/°K, so at 0°C, the output current ideally is 273 ...

Designing an analog circuit can be a frustrating experience, as noted by Nick Cornford in his Design Idea (DI), “ DIY RTD for a DMM.” With a fortnight’s struggle, I completed the design of 4 mA to ...

The circuit uses this diode as a temperature sensor (the temperature coefficient is about −2 mV/°C for silicon). During the negative half-wave of the input AC, while the MOSFET Q1 is OFF, the negative ...
