Read and transmit meteorological data

Transmit Wirelessly

Long distances and high elevations

Project Description

 System Block Diagram

Conceptual Sketch

Scout Tower

Mesh Network Solution

The range of the transceiver must be 1-2km

Network shall use mesh network protocol

Data shall be sent home once a day

Data logged on tower’s own memory

All components housed in a NEMA4 enclosure

Functional Requirements

Network shall be self healing

Wireless signal shall penetrate rough terrain

Wireless signal shall withstand various precipitation

Transceiver shall be plug and play

Non-Functional Requirements

Interface with data logger

Scout tower built-in data storage

Data logger design

Using our own microcontroller

Assumptions

Terrain can attenuate wireless signal

Topology could create bottlenecks in network

Climate could stress the operability of components

Limited access to information
