Read Data¶
HTTP Read Data¶
We need API KEY information for retrieving the data of temperature, damp, voltage, light etc. values like that which are sending Iot device.Datas which are sending from your Iot device can monitore with mobile devices like Pi, Android, iOs or your website.
For example; Assume that our device’s name “Temperature sensor” and it will be in the device additionally assume that our sensors “temperature” and “humidity”
Data Retrieving with Python 2, Python 3 Json¶
Get Example with Python Json: The number of data specified by results was read,by using the requests.get method from the IOTHOOK server Up to 99 pieces of data can be read with the results variable. If the results variable is not specified, only 1 data can be read. The format of readed data is json
The following output is obtained, by running the following Python script.
>>> [{'id': 502483, 'device': 17, 'field_1': '46', 'field_2': '6.70', 'field_3': None, 'field_4': None, 'field_5': None, 'field_6': None, 'field_7': None, 'field_8': None, 'pub_date': '2019-08-31T00:57:27.086837', 'remote_address': '88.242.132.150&python-requests/2.12.4&HTTP/1.1'}]
>>> 1
>>> 502483

IOT Data Fetching with Python PySide2¶
PySide2 is the official Python module that provides access to the Qt 5.12+ framework for Python projects. Before using PySide2, the following modules need to be installed
$ pip install matplotlib
$ pip install numpy
$ pip install PySide2
The installation of Python libraries has been done using pip. If pip is not installed on your system, you can visit the following address, https://bootstrap.pypa.io/get-pip.py, to download the file to your computer and run it.
Here, we will use PySide2 and Matplotlib to display the incoming data as a graph within a Window.
When the script is executed, we should see a window like the one shown below.
In this example, the interface design was created using QT Designer. For the widget,*Promote to …* option was used with the MplWidget class. In prepearing this example manap.se Manap and yapayzekalabs.blogspot.com Yapayzekalabs used this sites. You can find more resources at these sites.
- The test process was carried out with a device named 5 channel test with id number 230 in IoThook.
This device belongs to demo user
