Huth began his research into affordable open source alternatives, adopting the Arduino system and its wide variety of sensors. Huth built a solar powered prototype that sensed rain and water runoff and encased it in a waterproof kayaker’s lunchbox. A basic 2G GPRS modem was used to transmit sensor data to ThingSpeak, the IoT analytics platform that allows users to store, analyze, and visualize their data.
In order to deploy these remote environmental monitors (REM) in areas with no cellular connectivity, Hans worked with Sean Keane, an ADEQ intern, on reprogramming the Arduino to work with a RockBLOCK. For the purpose of monitoring discharges from a stocktank and to facilitate sample collection, a RockBLOCK-powered REM was successfully deployed at Horseshoe Draw near the border with Mexico. Given this success, ADEQ plans to deploy nine more cellular and RockBLOCK powered REMs throughout the state prior to the close of July, 2019. ADEQ is in the process of documenting time and money savings from respective deployments.
Huth documented his first environmental monitor’s development and deployment on YouTube to include links to source code for these inventions. Huth’s YouTube channel also includes chapters on building and deploying these REMs, and he is currently working on a new chapter summarizing code and deployment of RockBLOCK-enabled REMs.
