Use Rapid IoT as Panic Button

.

Overview

.

I am building a Panic Button using Rapid IoT Kit. In the project, I use Tap Detection as a mechanism to indicate there is a situatio of panic. To minimize false alarm, only tap count of greater than 5 will trigger an IFTTT applet which will send a notification on a mobile device. There is a Clear button for clearing the tap count.

Setup Rapid IoT

.

Follow this Hardware and Software Documentation to setup the IoT Kit.

.

Using Rapid IoT Studio

.

The IoT Studio is easy to use. There are many user references for this purpose:

• Rapid IoT Studio online IDE
• Launch IDE
• Rapid IoT Prototyping Kit

.

Using IFTTT

.

Create an IFTTT webhook at IFTTT website.

The trigger URL is of the form: https://maker.ifttt.com/trigger/{applet name}/with/key/{your key}

Codes

.

I modifid the code from Rapid IoT Weather Station source. I removed all the other sensors code, except the light sensor reading. I added the Tap Detection function and the code which update and clear the tap count. At the Application part, I add a WebIO which will trigger the "trigger panic" applet if the tap count is greater than 5.

ATMO_Status_t ClearTapCount_trigger(ATMO_Value_t *in, ATMO_Value_t *out) {
	ATMO_CreateValueUnsignedInt(out, 0);
	return ATMO_Status_Success;
}

The above code clears the tap count.

ATMO_Status_t Increment_performOperation(ATMO_Value_t *in, ATMO_Value_t *out) {
   return ATMO_PerformOperation(out, ATMO_PROPERTY(Increment, operation), ATMO_PROPERTY(Increment, operand), in);
}

And the above increments the count.

.

Summary

.

I use the Tap Detection in this project, but one can use other mechanism like Fall Detection and buttons on the IoT Kit to act as Panic Button. In this project, I did not build a proper mobile app for the Panic Button. As a future enhancement, ne such app can be built so that various settings and configurations can be made.
