Fresh water is a limited resource that is predicted to become more stressed and less accessible in the future. A large consumer of fresh water sources is the agriculture industry. As world population increases, the agriculture industry must also grow in order to meet rising demand. This need will only increase the stress on the already heavily used resource of fresh water. The Agriculture IOT Sensor System (AIoTSS) has been designed to give agricultural engineers the data they need in order to optimize their use of fresh water.
The AIoTSS is an array of inexpensive, battery-powered sensor nodes that are embedded into the soil in a field during a growing season. Sensor nodes consist of a thermistor soil temperature sensor and a capacitive soil moisture sensor. An Atmega 328P microcontroller is used to gather and store the data. A local data-gathering node connects to each sensor via Bluetooth periodically to gather data. Sensor data is then stored in an Amazon RDS database for analysis. Users have access to data through display systems and can use analysis of the data to optimize fresh water usage and maximize crop yield. The sensor nodes are removed at the end of the grow season with the crop, and can be recharged and stored for use in future seasons.
With data provided by AIoTSS the impact on our precious fresh water resources from agriculture can be reduced without sacrificing crop yields.
