Device
The Raspberry Pi Model Zero W is a $10 microcomputer that can run the open source Linux operating system. The "W" implies included wireless functionality through a Wifi and Bluetooth adapters that allow this version of the device to connect wirelessly to bluetooth and wifi peripherals. In this deployment, a single device is allocated to each bus is part of the transit network. We envision the device be included as a kit with the following components towards a complete deployment to ensure uninterrupted power and internet connectivity.
- A micro-SD memory card.
- A power source such as a solar-powered and charged USB battery kit.
- A mobile internet hotspot.
The MAC-address of the wireless adapter is used as a unique identifier of each device and can be integrated with fixed-route information to uniquely identify individual buses or the routes they operate on. While it is not required for proper functioning, the solar-powered battery requires access to a source of solar energy which requires the kit to be placed securely on top of the bus facing the sun.
