PBR1 Wristwatch Barometer for AP4

Changes in barometric pressure between a calibration and actual measurement will affect resistance readings: a change of 1kPa can cause a 1% error in measured resistance. An extreme change in the weather could have this effect, but altitude is normally a greater factor, the rate of change being 1kPa per 100 metres.The Wristwatch Barometer type PBR1, is suitable for monitoring local pressure.
