  • Measure environmental data throughout the car, including humidity, airflow, and temperature (see data acquisition SRR for more rationale)

  • Physical: Make it as small as possible (need input from mechanical/E-mech)

    • Discuss form factor and mounting with Cooling

      • Talked to Kaden Nguyen 10/12/24

        • Airflow sensor needs to be exposed - preferably back of board

        • Humidity/temp can be anywhere

        • Make as small as possible around PSOM

        • Mounting holes on corners

    • Airflow only one direction - can have stuff on the other side of flow sensor

    • Does not need to be waterproof

  • Interface: this board will send all environment data to the main Environment Leaderboard via internal Data Acq. Environment CANEnvironmentCAN

    • Will then be sent over TelemetryCAN to the telemetry module??

  • Modularity: Can pick and choose which sensors to use on each board during assembly – doesn’t require all sensors to be present

...

  • Cooling: Nose Intake, Tail Exhaust, Battery box intake/exhaust, internally in battery box multiple locations

  • any other systems needing environmental sensing TBD

Discussed with Parthiv Shah 10/26/24
