I wrote about how to collect data from DS18B20 temperature sensor with Raspberry Pi a few months ago, and this is an article on how to do some basic data analysis using Python with the collected DS18B20 temperature sensor data. Continue reading “DS18B20 data analysis using Pandas”
DS18B20 is a temperature sensor which communicates over a 1-Wire bus that by definition requires only one data line for communication with a host controller. I like DS18B20 as compare to other popular low cost temperature sensors for its accuracy and reliability. According to the DS18B20 data sheet, DS18B20 provides a digital Celsius temperature output with an accuracy of +/-0.5°C in the range of -10°C to +85°C.
