Project description
sensorhandler
Multipurpose sensorhandler, read the value from source & do somethings (send, save, trigger, ...) with it, as configed.
install
pip install sensorhandler
input
config.toml file on the current working directory. The contents of File is as follows:
[[sources]]
name = "dht22"
errorhandler = "errorhandler"
[[sources.values]]
name = "temp"
handlers = [
"send"#import os, "save"
]
[[sources.values]]
name = "humidity"
handlers = [
"send"#, "save"
]
[[sources.values]]
name = "humiditydeficit"
handlers = [
"send"#, "save"
]
[[sources]]
name = "mh-z19"
[[sources.values]]
name = "co2"
handlers = [
"send", "save"
]
The array of table sources is the array of data source sensor definition, consist of followings:
-
name: Sensor handler's name. The same name python file (with ".py" extention) will be dinamically imported and function read() on the imported module will be called. The return value of read() is expecte as a dictionally as key of value name and value like:
{'humiditydeficit': '15.9', 'temp': 26.8, 'humidity': 37.6}
-
values: handler difitition for each value, corresponding to the key of the dictionally of the return value of read() function.
-
name: value name
-
handlers: Value handler's name. The same name python file (with ".py" extention) will be dinamically imported and function handle(data_source_name, data_name, value): will be called with the Sensor handler's name, value name, and sensor value.
-
-
errorhandler: Error handler's name. The same name python file (with ".py" extention) will be dinamically imported for error handling of Sensor value reading. Currently, just stab.
How to use
as python program.
python -m sensorhandler
as python library.
import sensorhandler
print (sensorhandler.read())
