This paper presents a Smart Real Time Portable Multichannel Data Logger (SRTPMDL) prototype. This system is capable of reading multiple (analog and digital) inputs through sensors while displaying data on a smart phone. The objective of this prototype is to be efficient and low cost. Examples of the inputs read are voltage, temperature, current, pressure, humidity, and digital sensors. Any of those various data types could be implemented in order to achieve our goal in monitoring industrial machines, residential homes, and other possible applications. The SRTPMDL enables to monitor remotely and to save multi analog/digital signals used to detect possible errors that might exist on specific sensors/signals.
