Project Requirements

Marketing Requirements

MR1   - The system shall be able to communicate over the average length of a parking lot and shopping center in open space.

MR2   - The system shall be able to communicate at half the open space distance in the presence of typical RF signal obstructions.

MR3   - The system shall detect the presence of a dog inside a vehicle.

MR4   - The receiving device shall operate for more than 2 months before recharge.

MR5   - The system shall accurately read temperature values inside a vehicle. 

MR6   - The system shall alert users before harmful temperatures for dogs are reached.

MR7   - The receiving device shall fit on a keychain or in the user’s pocket.

MR8   - The system shall operate in conditions exceeding unsafe temperatures for dogs.

MR9   - The system shall be usable without an FCC license. 

MR10 - The system shall follow a simple installation procedure which can be completed by single user.

Engineering Requirements

ER1 [MR1] - The receiving device shall receive signals from 360 feet away in ideal conditions.

ER2 [MR2] - The receiving device shall receive signals from 180 feet away in typical use cases.

ER3 [MR3] - The system shall detect motion at least 1.5 meters from the doppler radar.
