Features & Capabilities

uSpectrum PAR is a wireless controller application designed for UPRtek handheld Spectral PAR Meters like the PG200N (FW 1.1.0.B25 or higher). This app enables remote analysis of light sources, allowing users to configure device integration modes and save captured data via Bluetooth.

The app offers six key features: Basic, Spectrum, PPFD Spectrum, CIE1931, CIE1976, and CRI diagrams for comprehensive light measurement. Users can visualize detailed light source information such as LUX, CCT, CRI, chromaticity coordinates (x, y), and peak wavelengths. It also provides absorption metrics including PPFD, PFD, and spectral components (PFD-R, PFD-G, PFD-B). Data can easily be shared via email, making light source analysis efficient and accessible.

User Reviews

Multiple users report that uSpectrum PAR requires an external Bluetooth-connected spectrum meter to function and does not work using only the phone camera. The app asks for location and file permissions that users find unnecessary. It often fails to detect the phone's own camera or Bluetooth, causing it to be non-functional on different devices like Samsung Note 8 and Google Pixel 4XL. Many users find the app confusing or difficult to use, leading to poor experiences and uninstallation.

Useless, want an external hardware

Never got to use the app since they required both file and location. Which is unacceptable you don't need to know where I'm at nor do you need access to files unless I decide to export something.
