ML-020P PAR Sensor:
The ML-020P PAR sensor is a device that measures photosynthetically active radiation (PAR), which is the portion of the electromagnetic spectrum between 400 and 700 nanometers that plants use for photosynthesis. The sensor typically consists of a light-sensitive detector and a housing that protects the detector and allows for easy mounting. The sensor can be used to measure the amount of light in an environment, which is useful for monitoring plant growth or for controlling lighting systems in greenhouses or other indoor growing spaces.
Small sensor ML-020 series are all-weather type compact sensors which are developed for measuring solar
radiation and artificial sun light in various wavelengths depending on the measurement purpose. Although these
are small sensors, they use collector which is specially designed to improve the cosine response and increase the
sensitivity; by the combinations of filter and photodiode for measurement purpose, 3 types of sensors are
By the combination of special filter and the sensor, the Small Sensor ML-020 Series have spectral response closer to the ideal spectral response. The temperature dependency is also within the range of 1% maximum.
The sensors are very small in size and weight (φ22x33mm, 65g), which is convenient for carrying and suitable for taking measurements of irradiance and illumination distributions.
The sensors can be used in all weather conditions allowing taking continuous and stable measurements.

- Compact design
- PAR response curve
- Glass dome plus diffusor optics
- Low temperature dependency
Designed for horticulture and agricultural applications, the photon active range of the compact ML-020P PAR or Quantum sensor is between 400 to 700 nm; that is, the photosynthetically active radiation (PAR), otherwise known as photosynthetic photon flux (PPF) or photosynthetic photon flux density (PPFD), is represented as mol/m/s (micromoles of photons per square meter per second).
The low output Voltage of the sensor can easily be converted to a 4–20 mA current or higher voltage using the MS–4–20 mA converter. The mV/mA converter can be pre-programmed and optimized within the operating range compatible with standard measurement equipment.
