Auhtor: Petr Šrámek

You ordered a few DS18B20 temperature sensors and after a few weeks of waiting, you finally received the shipment. You connected the sensor to your project and … nothing… Tried again … nothing.

Where is the bug? Your connection? Bad contact? Your code?

For solving of issue, Petr Stehlík (CZ) developed a smart code which tests your temperature sensor.

He received a lot of sensors which were not working properly hence he spent a time for developing of this “tool”.

Schematic and code is available on github https://github.com/joysfera/DS18B20-tester/
