While fully integrated smart sensors and devices are getting smaller and cheaper, communicating their data becomes the biggest cost factor. Conventional links like USB, WLAN, Bluetooth, ZigBee, and others are too expensive, when selling price shall drop below $ 5.-.

Implemented for a medication transport temperature-tracking device of a Swiss company, we demonstrate the unidirectional data transfer of 84 Bytes of Data from the LTI device (Long Term Indicator) to almost any smartphone in less than 10 seconds at almost no additional cost using only 3 LEDs.

Takeaway

Using just a button and a few LEDs, it is possible to transfer data at almost no hardware costs from a smart sensor device to almost any smartphone.

We demonstrate this with a proven design and product, but this can be adapted to almost any other device or application. The method is free to use and our intention is to make it public and thus to avoid patents blocking this.

Intended Audience

Interest in communications and/or electronics
