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. EnvironmentCAN
- 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
TODO: breakout system
- TVS for i2c, fuse, connectors
- pinouts for connectors on board silkscreen if also using for logic analzer debug points
- possibly need i2c repeater: https://www.nxp.com/products/interfaces/ic-spi-i3c-interface-devices/ic-bus-repeaters-hubs-extenders/level-translating-ic-bus-smbus-repeater:PCA9509

Context

Location of the board: Several boards will be located throughout the car as outlined below
