A block diagram of an RTD industrial temperature sensor. An RTD translates a physical quantity (temperature) into an electrical signal and is typically used to detect temperatures between –200°C and ...

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.

As cheap as the WCH CH32V003 MCU is, its approximately $0.10 price tag looks far less attractive when you need to start adding on external ICs for missing basic features, such as temperature measur… ...
