Each piece of cardio equipment in the gym will be equipped with a monitor that determines if it is occupied or not.
With the exercise area in the gym covering a large area of up to 900 square feet, and the concern for safety with errant wires, there is a need for wireless communication between devices using Bluetooth or WI-FI. A comparison between the two implementations is displayed below.
|Frequency||2.4 GHz||2.4,3.6, 5 GHz|
|Range||10 meters||32 meters|
Update Time: System must handle individual updates from all machines within one minute.
Accuracy: With updates being made very frequently, accuracy isn’t as important of an update was lost, but the occupancy-monitoring device must detect occupancy within 90%
FCC Regulations: Communication between all devices must be done within all FCC Regulations.
Power: The occupancy monitors will use standard AC power, as it is the same power supply that the equipment is also plugged into. Another alternative is a long lasting lithium battery but can run into issues on how long and what period of time it will last throughout the day.
Size: The system will be divided into single components that monitor each piece of equipment using a microcontroller resulting in a general size of 5.5×7 centimeters.
Durability: Since the monitors are in a gym, each component will need to withstand low impacts from accidental contact so each component will be placed in a plastic encasing.
