The patent refers to a photodiode-based pyranometer for the visible spectral range (approx. 400 to 750 nm), whose principal characteristics are: accuracy, ease of connection, immunity to noise, remote programming and operation, interior temperature regulation, cosine error minimisation and all this at a very low cost, tens of times lower than that...

Context 1
... lamp, which was placed 50 cm from the photodiode, was used to emit the illuminance to be measured. Figure 5 shows the response of photodiodes (connected to a 0.1 Ω shunt element to carry out measurements in short-circuit) to different illuminances. The response curves are certainly quite similar and the one showing the lowest response was that of OSD5-5T. ...
