Home Automation

Your deliverable to the client is the Design Solution Proposal which should include:

1. 1)  Summary section. Summarize your understanding of the current problem, along with any unique constraints

   and/or conditions under which the system will have to operate.

2. 2)  Prior Art section. Discuss 2 to 3 previous solutions to similar problems found in the literature.
3. 3)  Measurements section. Give a list of the specific physical parameters that are important to be measured and your estimate of an appropriate time interval between measurements. Explain your reasoning to justify the estimates. For example, some physical phenomena change mode rapidly than others, and may require being sampled more frequently, once a second, once a minute, once an hour, once a day. Include in this list those measurements that are explicitly stated or inferred in the problem statement, and any others that in your judgement should also be measured.
4. 4)  Controls section, if applicable. Not all designs require an actuator that responds to commands from a controller. If present, give the types of actuators and their typical update rate.
5. 5)  Proposed Solution section. An outline of your general solution strategy to the Sensor/Actuator Network design, that includes:
   1. A description in general terms of the characteristics of the sensors/actuators and End Nodes:

      • The type of sensors required on each End Node to measure the various physical phenomena • The type of actuators required and what they control
      • The approximate number of End Nodes required to cover the scenario
      • Choice of wireless transmission technology and its maximum range

      • Your recommendation of energy source for each End Node

   2. A diagram/map of the project area where the sensor network will be deployed
   3. Annotations on the diagram showing typical placement of End Nodes, and Router/Concentrator Nodes

      taking into account the max wireless transmission ranges of sensor & router/concentrator nodes

6. 6)  End Node Detailed Design. Supply quantitative answers to the following questions.
   1. Bill of Materials. Recommend actual commercially available parts that are suitable for use in the End Node. Supply a manufacturer and part number for:

      • The End Node microcontroller (consider sufficient I/O pins for the sensors and actuators) • Each type of sensor and actuator
      • An energy source

   2. What wireless technology do you recommend for communication between the End Nodes and Router/Concentrator Nodes? What transmission range does it give?
   3. How many End Nodes do you estimate are required to cover the physical space of the scenario? Consider wireless transmission range and router-to-end node service ratio.
   4. Estimate a typical End Node’s battery life. Use the parameters specific to your application.
