Abstract

The optimization and performance of many systems require data collection for the temperature variation of solids, liquids, and air parameters that vary from one location to another. For example, monitoring the performance of an Atmospheric Water Generator Device that utilizes geothermal heat rejection to condense vapor in the humid air. This device requires air parameters, water temperatures, and soil temperature variation to be measured to understand the system. This paper presents a capstone project that involved the design and implementation of an inexpensive data acquisition system that utilizes off-the-shelf components. Twelve parameters are collected: air inlet and outlet temperatures and humidity, water inlet and outlet temperatures, and soil temperature from two to eight feet at one-foot increments. The Raspberry Pi 4 with MCP-9600 chips, which runs on the I2C protocol, was used in this project. The I2C works by using an address system that allows the Raspberry Pi to distinguish between multiple sensors. The sensors, setup, circuitry, and code details are presented here. The system's performance, possible improvements, and the educational experience of an international capstone are also discussed.
