Download Ds18B20 Raspberry Pi 5V Gif. However, this requires us to input a command every time we want to know the temperature. I read somewhere that raspberry pi gpio pins will burn if we directly feed 5v!
Raspberry pi DS18B20 (saunan lämpötilamittari) - Webroni from webroni.net They're the same size as a transistor and use only one wire for the data signal. I believe the ds18b20 dataline uses some sort of open collector transistor or open drain mosfet to drive the dataline. They're also extremely accurate and take.
If you're using a newer raspberry pi (or an arduino) the answer is no.
However, this requires us to input a command every time we want to know the temperature. The raspberry pi gpio is connected to the temperature sensor ds18b20 via one wire interface. Ds18b20 not detected by raspberry pi. Raspberry pi stack exchange is a question and answer site for users and developers of hardware and software for raspberry pi.
