PAR (PPFD) Measurement for iPhone. This clip attaches over the iPhone front camera and works with the MoeuPLTest PAR app to measure PPFD (μmol/m²/s) from grow lights. An integrated diffuser helps distribute light across the camera sensor during measurement. Download MoeuPLTest PAR App First Before purchasing the clip, you can download the MoeuPLTest PAR app to explore the interface and understand how measurements are displayed. The clip works together with the app and attaches over the iPhone front camera to measure PPFD (μmol/m²/s) from grow lights. Common Grow Light Profiles Included. Includes light source profiles for Full Spectrum + 660 nm (Deep Red), Incandescent, and Ceramic MH, which are commonly used in grow lighting. Additional light source profiles are available within the application when needed. The MoeuPLTest PAR app includes additional light source profiles for different grow light types, including: Full Spectrum, Red + Blue, Deep Red, Blue + White, Fluorescent, HPS Sodium, Sunlight. These profiles can be enabled within the application when needed. Optical Diffuser for PPFD Measurement. Includes a white optical diffuser positioned above the camera to distribute incoming light across the sensor during grow light measurement. Measurement History & iOS Compatibility. Measurement records can be stored and reviewed within the MoeuPLTest PAR app to compare lighting adjustments over time. Compatible with iPhone devices running iOS 17 or later using the MoeuPLTest PAR iOS application. Android devices are not supported. Measure Grow Light Intensity with Your iPhone The MoeuPLTest PAR Clip allows compatible iPhone devices to measure PPFD (Photosynthetic Photon Flux Density) using the phone camera together with an optical diffuser. Attach the clip over the front camera and use the MoeuPLTest PAR application to measure light intensity in μmol/m²/s, helping growers evaluate lighting conditions for indoor plants, hydroponics, and greenhouse setups. This compact clip works as a portable measurement accessory without requiring a separate handheld PAR meter. Designed for Common Grow Light Spectra The MoeuPLTest PAR app includes several light source profiles commonly used in horticultural lighting. Included profiles: Full Spectrum + 660 nm (Deep Red) Incandescent Ceramic MH Additional light source profiles are available within the application for other lighting types, such as: Full Spectrum Red + Blue Deep Red Blue + White Fluorescent HPS Sodium Sunlight These profiles allow the application to adjust measurement behavior for different spectral characteristics. Optical Diffuser for Stable Measurements The clip includes a white optical diffuser positioned above the phone camera. The diffuser spreads incoming light across the sensor to help improve: measurement stability repeatability consistency under different spectra This design is intended specifically for PPFD measurement of horticultural lighting systems. Record and Review Measurements The MoeuPLTest PAR app includes a history function that allows users to store and review measurement data. This can help growers evaluate lighting adjustments such as: changing lamp height adjusting dimming levels comparing fixtures monitoring lighting distribution Measurement records can be reviewed over time within the application. Compact Clip Design The lightweight clip attaches directly to the front camera area of compatible iPhone devices. The portable design allows PPFD measurements to be taken in various growing environments, including: grow tents indoor plant shelves hydroponic systems greenhouse installations Application Compatibility This clip is designed to operate with the MoeuPLTest PAR iOS application. The application is available for compatible iPhone devices. Android devices are not currently supported.
