Measure temperatures with a 1-wire DS18B20 sensor and Raspberry Pi

In our article DS18B20 Temperature Sensor with Raspberry Pi we detailed how the Raspberry Pi can be used to take temperature readings from a ds18b20 temperature sensor via the i2c protocol. Here we will expand that article to explain how multiple temperature sensors can be copnnected to the Raspberry Pi - particularly useful for example in solar water heating pump controllers and other differential temperat ...
