IOT SYSTEM WITH Thinger.io PLATFORM, PART 3
This is the continuation of my previous post: IOT SYSTEM WITH Thinger.io PLATFORM, PART 2
ADDING WIDGETS
We activate the widget editing mode by clicking the right button as shown in the image below.
STEP 1.- ON/OFF WIDGET
The first widget is to control the LED diode connected to pin 13 of our Arduino NANO 33 IoT board. The Widget tab fills up as shown below.
The On / Off State tab fills in as shown below.
The Display Options tab fills in as shown below.
The created Switch is shown in the image below.
STEP 2.- SLIDER WIDGET
This widget helps us to control the LED diode connected to pin 12 of our board. The Widget tab is shown below.
The Slider tab is shown below.
The Display Options tab is shown below.
The widget created is shown in the image below.
STEP 3.- GAUGE WIDGET
The Gauge widget helps us to monitor the data measured by the TMP36 temperature sensor. The Widget tab is shown below.
The Gauge tab is shown below.
The Display Options tab is shown below.
Finally our widget is shown below.
TEST
A test done with the PC is shown in the video below.
Finally we see in the video below a test made with the android application thinger.io
Thinger.io app you can download here.
CONCLUSION:
Thinger.io is a good option to learn how to use iot tools without spending money, since it is an open source iot platform.
This platform has its limitations, since as we can see in the console, we can only connect 2 Devices, configure 4 Dashboards. We also depend on library updates and we may not be able to use the latest sensors, however I like this platform to do various hands-on experiments for free.
The switch button had very little time delay and can be used to remotely turn on and off medical equipment, eg a mechanical ventilator, an oxygen tank, etc.
2) The slider never blocked and I'm satisfied with its operation, it can be used to control the air conditioning where a patient receives medical treatment, etc.
3) The gauge was updated every 5 seconds and the values it showed in the widget were the ADC data from 0 to 1023 bits from the temperature sensor tmp36. Excellent way to guide ourselves qualitatively how the temperature varies in a hospital room with patients.
