Subsystems Design

Table of Contents

Through the subsystems design process, extensive initial research was completed in order to prove feasibility of the project. Research was also done on selection of components, which developed into a top level BOM.

Controller

 Atmega 328P Microcontroller

Atmega 328P Microcontroller

Atmel's ATMega328P 8-Bit Processor in 28 pin DIP package with in system programmable flash

Features:

Power Electronics

Sensors

Three environment variables will be monitored - ambient temperature, ambient light, and panel output voltage. These three environment variables provide the necessary knowledge to judge the presence of snow.

Ambient Temperature Sensor

Ambient Light Sensor

Additionally, type K thermocouples will be used, in conjunction with the AD595 thermocouple amplifier, to monitor panel temperature for control feedback.
