Captis: Sensor Agnostic IoT Solution

The Captis can be used in a wide variety of applications and with a variety of sensors, eliminating the expense of human resources required to manually
visit remote locations to collect data, and the risk of human error in gathering and reporting data.

In the case of the Captis Multi+ and Multi, multiple sensors of different input can be used simultaneously to create comprehensive monitoring solutions.
