thermocouple-max31855
Reads data from the thermocouple amplifier MAX31855.
var tessel = require('tessel');
var thermocouplelib = require('thermocouple-max31855');
var sensor = thermocouplelib.use(tessel.port['GPIO'], {
cs: 0,
poll: 10
});
sensor.on('measurement', function (data) {
console.log(data);
})
Usage
To install the library:
npm install thermocouple-max31855
To include it in your code:
var thermocouplelib = require('thermocouple-max31855');
var sensor = thermocouplelib.use(port, { /* options */ });
# sensor.read( function (err, data) )
Create a measurement reading from the thermocouple. Returns data of this structure:
{
fault : 0,
fahrenheit : 86.9,
shortVCC : 0,
celsius : 30.5,
internal : 22.0625,
openCircuit : 0,
shortGND : 0
}
# sensor.on( 'measurement' )
Every time a reading is made (using the .read()
function or through the .poll
option) this event is emitted. See .read()
for its data structure.
