Photosynthetically Active Radiation (PAR)¶

Use the MultispeQ’s PAR sensor to measure light intensity (400-700nm) in µmol photons × s⁻¹ × m⁻², which represents the Photosynthetically Active Radiation.

This protocol outputs the PAR value, as well as the raw values for the red, green, and blue channel of the sensor.

Import

Example: Import par into a script¶

import jii_multispeq_protocols.par as _par

Protocol

[{'averages': 1, 'environmental': [['light_intensity', 0]]}]

Analysis Function

_analyze(_data)[source]: Return the PAR value, as well as the RGB channels raw values.

Analysis Example (requires JII-MultispeQ package)¶

from jii_multispeq import measurement

## Take a measurement using the MultispeQ
data, crc32 = jii_multispeq.measure(port="<Selected Port>", protocol=_par, filename=None, notes="")

## The analyze function of JII-MultispeQ helps to provide the correct format
output = measurement.analyze( data, _par._analzye )

## View Analysis output (as table)
measurement.view( output )
