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

---|---|---|
Form Factor | PSOM daughterboard with connectors (<4cm) for breakouts (sensor + passives) as to not disrupt airflow | PSOM daughterboard with SMD components |
