Read temperature in degrees Celsius. Temperature can be converted to Fahrenheit scale using celsius-to-fahrenheit node.
read-temperature
@/read-temperature
Read temperature in degrees Celsius. Temperature can be converted to Fahrenheit scale using celsius-to-fahrenheit node.
DEV@/mcp9808-device
A MCP9808 device.
UPDpulse
Update. Trigger read.
DONEpulse
Pulse on read.
TempCnumber
Temperature in degrees Celsius.
To use the node in your project you should have the wayland/mcp9808-thermometer library installed. Use the “File → Add Library” menu item in XOD IDE if you don’t have it yet. See Using libraries for more info.
