Pressure pick-up MPX 4115 AP Assembly of the calibration
Pressure pick-upMPX 4115 AP
Characteristic of calibration: P=277*Vs+160 (hPa)
The photodiode or the sensor of luminosity: A photodiode makes to measure the luminous intensity. Its
measurement is expressed in lux.

Luminosity according to the tension:
The sensor of moisture
On the left we have the sensor which is welded onto the plate, then on the right is located the diagram of the assembly. We placed two resistances so that the tension which arrives at the Mermoz chart is of 3.3V maximum.

The Wind vaneIt is used to give the direction of the wind which is
the source from which the wind comes.
