Project Scope

To design an environmental monitoring system that can be used in rooms and data racks to monitor and alert the temperature, power and other environmental attributes using one or more USB powered environment sensors that are extremely inexpensive and flexible in configuration. The system will consist of nodes and a central server task that stores and displays historical data and provides alerting capabilities.

Considerations

• The max number of sensor nodes in a system
• Power
  • Sources
  • MCU power consumption
  • Sensor power consumption
  • Power saving strategies
  • Voltage requirements - 5v, 3.3v 12v etc.
• Communications
  • Physical - Method of communication (Wifi, Bluetooth, LoRaWAN, Zigbee etc.)
  • Wireless Range
  • Bandwidth / Number of sensors on each server
  • Protocol
• Data formats
• Node setup and Configuration
• Device Reliability
• Update/refresh frequency
• Component Cost
• I/O
  • Number of sensors on each node
