Pepper Oak Farms, a company that grows their own olives for olive oil and has approximately 40,000 olive trees, is in need of an efficient way to monitor the soil and atmospheric conditions that are critical to the cultivation of their trees. The company at the moment only has two sensors and has to manually place the sensors at different locations to collect data on soil moisture and temperature. This is expensive, time consuming, and a lot of effort on the owner’s part to go out on the fields to collect this data. As a solution, the company would like to create a wireless mesh network with different nodes throughout the land to monitor and collect data from the sensors.

The project goals are to implement this wireless mesh network with enough nodes in the network to cover most of the area on the land and for the project to be self-monitored. To help cover costs, we will be using modules that use Zigbee IEEE 802.15.4 wireless protocols and standards which are used for low power consumption and have a range of up to 100 meters. The modules will be interfaced with Texas Instrument’s Tiva C microcontrollers that will collect the output of the sensors to be later transmitted to the home network.
