Can you help me out on this one??

I deleted it and still worked Reply. Invalid GPIO numbering mode: Frax on July 12, at 8: Alejandro lituma on October 28, at 6: Alejandro Lituma on October 28, at 6: Filip on September 22, at 9: What is the white colored board where the Temperature Sensor is fitted called? For vatasheet with multiple DS on a single 1-Wire bus.

Sven on May 4, at 18b0, I am very new to this but what do you mean by address. Read further to know why these parameters are important. Madison on March 29, at 2: Jorge on April 17, at 8: You have to read through it to understand how to communicate with the sensor.

Danang on May 31, at Last commit 13 Jan by Erik Olieman. Shandabert on May 23, at 5: That should just about wrap it up! If you are planning to interface it with Arduinothen you need not worry about all these.

Digital temperature sensors are typically silicon based integrated circuits. The sensor works with the method of 1-Wire communication.
