LAIIER’s evaluation kits have been designed to help you evaluate our technology for whichever use case is required. This user guide will instruct you through setting up the relevant sensor hardware and software to allow for effective data collection and/or visualization.
This kit is the Trent Evaluation Kit that is suitable for measuring the level of any liquid within a container. Each kit comes with one Trent Evaluation Board plus a board enclosure and three Trent Sensors.
After following this user guide, you will be able to scope the performance of these sensors and test their suitability for your application.
Theory of operation
Our Trent Sensors are based on capacitive sensing. Conductive ink is printed into a unique pattern that creates three electrodes: An environment reference electrode, a liquid reference electrode, and a level electrode.
Trent Evaluation Board
The evaluation kit contains the Alfa Board PCB. This PCB has been manufactured specifically for the Trent Sensors and its future updates. It includes a microcontroller chip, FFC connector, power switch, and a Micro USB output port. You may notice an Arduino footprint has been used on the board which will allow for further capabilities in the future. The Micro USB port outputs serial data of the sensor's measurements which is explained in the instructions.
