DS18B20 Temperature sensor
Description Links Attachments
This well-known digital thermometer can measure temperature from -55 ° C to 125 ° C. This sensor has a one-wire interface, which means that all communication is only 1 data line. In addition, it is possible to connect several sensors to this data line and to feed these sensors over the same data connection.

SolipseEdit: I got away with using the OneWire library alone which includes an example for DS18x20 probes, and only in parasitic mode (Gnd and Vcc on Gnd + pullup on DQ) the library is able to make the reset work and read a new value with each request!
SolipseI have tested all available Arduino DS18B20 libraries, and I cannot get this component to work correctly. At best the initial temperature is obtained but remains frozen unless a reset is performed. The probe is found but does not return its OneWire address, this may be a reason for this malfunction...
Wilfried Verpooten Delivery was super fast
I have been a satisfied user of this product for over 10 years.
Paul Gerrit BakkerI am not one hundred percent convinced whether this is an original Dalas component, but connected in the 'normal' way, the thing works fine. I have not (yet) tested the so-called 'parasite power' mode.
