Suggested circuit for driving DS1820 thermometers
This is 1-wire driver with minimal component count. Widely available components are used. One general purpose PNP transistor, there resistors and one DIL socket as connector and component holder. NO PCB is required. Resistors R2 and R3 are inserted for current limiting protection of the processor. Fuse F1 is to prevent possible short circuit. The circuit should work also without R2 and R3 giving only R1 and Q1.
