Sistema sensor autònom sense fils de baix consum per al control d'il·luminació i reg en cultius d'hivernacle

Abstract

The project aims to implement a system of irrigation and lighting control for a greenhouse. To perform such control, the system must sensors to measure various parameters such as ambient temperature, relative humidity, ground humidity and light intensity. Once measured these values, the sensor system must send orders for the different actuators and also send ,via Wireless, these data to our Labview application to be displayed on the screen and be able to study these parameters based on time. The sensor system must be performed with a low power microcontroller PIC18 for the system to be autonomous with little energy supply. The PIC will be programmed in C using the FSM style programming. The first programs will be simulated in the virtual simulator Proteus to detect bugs more effectively. After performing the simulations, the program will be loaded into our physical PIC on our testboard where we find that everything works as we simulated. In choosing sensors, it will try to work with either analog and digital sensors. Regarding the sensors with digital interface, it is important to conduct a study of its communication protocols. Finally, after making the final prototype in our testboard, our printed circuit board (PCB) of our sensor system will be designed with Eagle and, if possible, the machining of the PCB will be done as well.
