## Questions & Answers

**Q: Can i use this to verify a uv cleaner?**
A: If by “uv  cleaner” you mean a disinfectant germicidal uv light this would not be useful as germicidal uv is uvc a shorter wavelength than the uva. and uvb. that the diode responds to.

**Q: Using bright sunlight as source, can the output be measured by a volt meter (~1M ohm internal resistance)?**
A: Yes, connect to 5V to +/- and the measure Out with respect to - on the voltmeter

**Q: can this be connected to a multi meter? How Please**
A: Yes with the following limitations: The sensor is calibrated to give UV index from 0 to 1 Volt, decimal values represent UV index, say 0.7 = a UV index of 7, so an appropriate scale would be easier to read.  A 0-1 Voltmeter with high impedance would be better.  Warning, though, the sensor is heat sensitive and may not work in the bright (it cuts out and is not harmed, but use may be limited) sun, lol !!, and if the meter is low impedance this may exacerbate the issue.  Can use batteries, 4.5 - 5 V and get shelf life with high impedance meter.
