Smart Plant Irrigation & Monitoring
The challenge: Precision is essential for optimal results in agriculture. It is important to know the optimal time for irrigation, considering the environmental conditions. Our challenge was to collect data about the plant’s environment, and to broadcast the data to a smartphone application.
Our professional solution: We developed a parameter monitoring system of the plant, which is battery activated and charged by a small solar cell. The system reports different data, such as humidity, temperature, fertilization levels, salinity and light intensity according to wavelength. In this manner, we can ensure that the plant receives the necessary conditions for its growth and operate the irrigation mechanism at the right time and only for the needed amounts.
Technical specifications: The electronic design is based on the CC2640 MCU, which is a BLE integrated processor by TI. We constructed a PCB circuit with 4 layers, assembled the components and performed board bring-up and testing. We also wrote embedded software using TI RTOS, in a Code Composer Studio IDE environment.
