The Maxim DS18*20 series temperature sensors are widely used due to their reliability, accuracy, and ease of use. They communicate over a single contact serial interface called 1-Wire, which makes them easy to integrate into projects. The Linux kernel's built-in w1_therm driver enables these sensors to work on any Linux machine with the appropriate physical interface. Telegraf's temp input plugin can read data about temperature sensors from the filesystem during each collection, but it currently only supports a single sensor due to an issue with the DS18*20 sensors and the gopsutil library used by Telegraf. A workaround is to use a Python script that reads the data and executes it through Telegraf's exec plugin. The author plans to iterate on the built-in temp plugin to make it support multiple sensors, potentially by adding a device name field to the SensorKey struct in the gopsutil library.
