MaGiDeL Posted February 12, 2015 at 10:02 AM Share Posted February 12, 2015 at 10:02 AM Hello everyone. Only yesterday I discovered your devices and I'm already crazy for them! They are awesome! especially for documentation! First of all, sorry for my english! I am looking for a sensor for the solar radiation. I need the measurement of radiation in W / m2 I could use the "Color Bricklet"? From this Bricklet I get the measure of illuminance in Lux. Is it possible to obtain the measurement of solar radiation? There is another device? I read in another post that the maximum illuminance of "Color Bricklet" is 100,000 Lx. This measure corresponds to about 790 W / m2. Is it small as a measure for the solar radiation? In my city, in the summer, the solar radiation easily exceed 1200 W / m2. Please, let's enlighten!

borg Posted February 13, 2015 at 09:44 AM Share Posted February 13, 2015 at 09:44 AM In full bright daylight the illuminance can indeed exceed 100000 Lux, so you wouldn't be able to measure that with the Color Bricklet. See here: http://en.wikipedia.org/wiki/Daylight Edit: Just for completeness since it may help others: We discussed this over email and came to the conclusion that for the university research he is doing he needs a somewhat specialized solar radiation sensor. Most sensors that are for a specific field do have a 4-20mA output. So the Industrial Dual 0-20mA Bricklet is probably the right thing to go with here.

MaGiDeL Posted March 2, 2015 at 12:37 PM Author Share Posted March 2, 2015 at 12:37 PM I resume this discussion to understand the difference in illuminance (lx) between Ambient Light Bricklet and Color Bricklet. The first sensor (Ambient) measures up to 900 lx, the second up to 100.000 lx. Is it correct? Thankyou for your replay Mario Quote Link to comment Share on other sites More sharing options...
borg Posted March 2, 2015 at 01:11 PM Share Posted March 2, 2015 at 01:11 PM Yes, that is correct. The Ambient Light Bricklet is more usable for deciding if there is or isn't light. It is not really good at measuring illuminance . Quote Link to comment Share on other sites More sharing options...
