SparkFun has recently released the Digi X-ON LoRaWAN development kit an all-in-one IoT development kit designed to simplify the setup and deployment of ...

In this article, we will learn how to similar speed sensor using Arduino and IR sensor. By setting up the two IR sensors at a fixed distance from each other, we can track the time it takes for the ...

Biosensors are devices used to detect the presence or concentration of a biological analyte, such as a biomolecule, a biological structure or a microorganism. Biosensors consist of three parts: a ...

Specifically, this work adopts a capacitive sensing mechanism to recover information from the sensed chemical signals. Our testbed demonstrates a notably higher transmission rate than previously ...

THIS CODE IS OBSOLETE * It needs to be updated to be compatible with changes to the ESP32 standard libraries. Also, if fine granularity control is required, it needs to use long int arithmetic instead ...
