Abstract
This paper presents the design of a level sensor for the purpose of liquid level sensing and monitoring using capacitive sensing techniques. Conventional techniques have many drawbacks with respect to accuracy and they cannot be used reliably for remote sensing. The design proposed here uses three capacitive sensors and a capacitance to digital converter IC integrated onto a sensor Printed Circuit Board. The sensor PCB is attached to the walls of the container and this allows the measurements to be made without any contact with the liquid. The sensing mechanism is independent of the liquid or the environment in which it is placed. The levels are uploaded onto a database located at a local server, and this data can be easily accessed by the user as per his requirement. Further, an android application has been developed for monitoring the liquid levels conveniently.
