A new sensor which accurately measures the Direct Normal Irradiance (DNI) without the requirement of a sun-tracker. It features a rotating mirror, which only reflects the sunbeam onto a thermal detector. The pulsed analog output can work with dataloggers with a pulsed analog input or peak hold function. The analog pulse (0-5V) is proportional to the DNI.  

Optional control box with GPS antenna (C-Box) can be used to connect MS-90 and any pyranometer to create a digital solar monitoring station measuring Direct Normal Irradiance (DNI), Global Horizontal Irradiance (GHI), and calculating Diffuse Horizontal Irradiance (DHI). This system provides Modbus 485 RTU output for all parameters from a single cable.

A revolutionary method to capture the direct sunbeam. MS-90 is a ...
