py-temperature-reader
Python application to read DS18B20 1-wire temperature sensor and sends data to configured recorders. Read frequency can be configured in config.json
by setting the property read-interval
in seconds.
{
"read-interval": 30
}
Recorders
A recorder is where the data read from the sensor will be sent. Multiple recorders can be configured at the same time using config.json
Existing recorders are:
- File
Some recorders has a format
configuration that can be used to format the output of the data. Fields that can be used in the string format are:
- device_id: the id of the sensor read
- timestamp: date and time of the read
- celsius: the value measured in Celsius
- fahrenheit: the value read in Fahrenheit
Print recorder
Print the data received through the console using the string format configured in format
.
{
"recorders": [{
"type": "print",
"config": {
"format": "{device_id} C {celsius} / F {fahrenheit}"
}
}]
}
File recorder
This recorder will create a file for each sensor read using the device id of the sensor as file name. The files will be stored in the path configured in container
with the extension specified in extension
. The data read from the sensor will be write using the string format in format
.
{
"recorders": [{
"type": "file",
"config": {
"format": "{timestamp},{celsius},C",
"container": "/temperature/",
"extension": ".log"
}
}]
}
