Exercises

1. Draw a block diagram of the computing architecture for a system to measure and report weather data 24 hours a day at 5-minute intervals using SMS text messages. The system is battery powered and relies on solar cells to recharge the battery during daylight hours. Assume the weather instrumentation consumes minimal average power, only requiring full power momentarily during each measurement cycle.
2. For the system of Exercise 1, identify a suitable commercially available processor and list the reasons that processor is a good choice for this application. Factors to consider include cost, processing speed, tolerance of harsh environments, power consumption, and integrated features such as RAM and communication interfaces.
