About BSEC calibration
IAQ, CO₂ equivalent and breath VOC come from the Bosch BSEC library running on the board. Values are withheld until accuracy reaches 1, because BSEC is still stabilising before that. Full calibration needs days of continuous operation. The CO₂ figure is estimated from VOC and is not a real CO₂ measurement.

The board is accelerating, so gravity is not the only component of the reading and these angles are unreliable until it settles.
How orientation is estimated
Roll and pitch are derived from the LIS3DH gravity vector. Yaw is not shown
because it cannot be measured: this board has an accelerometer and no
gyroscope, and rotating about the gravity axis does not change what the sensor reads.
The model is built from the real board outline and part placement in
techmaker-board.brd; component heights are representative.
