One-wire temperature sensors like the DS18B20 can measure temperature with a minimal amount of hardware and wiring. These sensors use a digital protocol to send accurate temperature readings directly to your development board without the need for an analog-to-digital converter or other extra hardware. You can get one-wire sensors in different form factors like waterproof and high-temperature probes–these are perfect for sensing temperature in many different projects and applications. With just a few connections and a WipperSnapper device, you’ll be sensing temperature in no time!
This guide explores how to connect a DS18B20 one-wire temperature sensor to a board supported by the WipperSnapper firmware. You’ll send its temperature data to be logged by Adafruit IO. All without any code!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
