A genuine Maxim sourced DS18B20+ One Wire Digital Temperature Sensor. The DS18B20+ is the perfect low-cost solution for a range of Raspberry Pi and Arduino temperature control and data-logging projects! The DS18B20+ measures temperature in degrees Celsius with 9 to 12-bit precision and includes an alarm function with nonvolatile user-programmable upper and lower trigger points. Sensing range is -55C to 125C (accurate to ±0.5°C over the range of -10°C to +85°C), and each sensor has a unique 64-bit serial number hard-programmed enabling the use of a number of sensors on a single data bus.

The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor, and can be powered on the Raspberry Pi's 3.3V power line.

Note: Image is a representation and may show another brand, however we only ship authentic Maxim sensors.

DS18B20+ One Wire Digital Temperature Sensor

Works like a magic with the external resistor added and connected to the bcrobotics irrigation hat for pi zero.

Used as a cold junction sensor for my modified T-962 Infrared Reflow Oven and it works well in 1-wire mode.

DS18B20+ One Wire Digital Temperature Sensor

Great sensor, accurate to 4 decimal places! After some tinkering I was able to get it working with Rust on an Arduino Nano 33 IoT

As described these are true Dallas sensors. Had many issues with clones from other vendors but these work without issue.

These sensors are very good as a component for building a domestic environment logging project. Very simple to work with and do exactly what they say.

DS18B20+ One Wire Digital Temperature Sensor

I enjoyed learning how to wire this up and to run three of them on the same RaspberryPI (the great joy of the raspberryPi). I was pleased to see that they agree on temperature when placed inside an insulated box. Not yet got round to wiring up the room with sensors is different places but one day maybe.
