CDC Pi Weather Station Has A New Sensor The 1Wire DS18B20
Time to tackle the 1Wire sensor
After the furore of last weeks success we’re back down to earth with a bit of a bang. We’re now trying to code the Raspberry Pi so it will read, and more importantly broadcast the readings from the 1Wire sensors to Plot.ly, the MET office or an alternative means of hosting the data online. The 1Wire sensor is already waterproof and designed to run in series with other 1Wire sensors which would greatly help with the expansion plans for the project. Although the Bosch BMP180 and the associated code worked, the sensor isn’t designed to be outdoors and nor does it measure water temperature. So I’ve turned to the 1Wire system.
