Drivers

1-Wire drivers need to be loaded in order to create the connection between the physical sensor and the rPI. You can load them from the terminal:

sudo modprobe wire
sudo modprobe w1-gpio
sudo modprobe w1-therm

Code

var sense = require('ds18b20');
sense.sensors(function(err, ids) {
  // got sensor IDs ...
});

// ...

sense.temperature('10-00080283a977', function(err, value) {
  console.log('Current temperature is', value);
});
