The company Sensefarm develops in the field of precision agriculture, more specifically a product for measuring and logging information on local environmental conditions. The collected data is transmitted to a remote server using GSM technology. They are looking into ways to improve their product. The purpose of this project is to evaluate the M66 GSM module and the accompanied OpenCPU technology. In the current product the GSM module is only used for the communication with the server. All other processing is done by a dedicated processor. The OpenCPU technology allows for running customized firmware on the GSM module, possibly allowing it to take over the responsibilities of the dedicated processor. An application implementing all the necessary functionality was developed to test this capability. The finished application was able to fulfill all the requirements specified, although it was not able to be tested in the field.
