diy par meter.... I just bought a quantum sensor (sq-120) and use it with a multimeter. I wonder how the diy compares, I might try and build one as it seem easy enough. I'm wondering what the range of the sensor is, the apogee website leads you to believe the sq-120 reads from 400nm-700nm when in fact according to the manual the range drops of sharply at 650nm.

Anyone know if hydrofarm's quantum sensor/par meter is even worth buying?

Growers house says it's accurate and they use it constantly on led panels of course........they sell it ;-)

My gut says no due to how cheap it is.......

Any thoughts?

I only have a piece of crap multimeter and was hoping that it wouldn't work with the sensor so I had a reason to purchase a new meter, it seems to work just fine. I was thinking about the Fluke 115 or 117 but am interested in what your recommendations are goud

Also I can't find a price for the LI-190 but does look like a better sensor than the SQ-120 according that pdf you dropped earlier. I did find a pdf on a BC government website about the Construction and Testing of an Inexpensive PAR Sensor, it uses licor part and was a quick read.

thanks bros... epic...ive posted this pdf... i underline it now... the next yumpu link dont go now for me... its the same pdf too...

...my crazy idea its a diy meter/s with various sensors, maybe 3 or 4 or more diferent sensors, for diferents things, its dificult to me explain you, english its a terrible wall to me...

...but similar way to depredator vision, infrared, uv vision, sensor 1, sensor 2, etc...

...the sum of all sensors give us a better "vision" or lecture of all data,...

...the range of diy i linked its 400-700 ...but in my crazy diy idea... others sensors give us others range in nm, on infrared zone and ultraviolet zone, maybe with sensors for exterior, yeah for greenhouses too,

...the calibration of diy par meter is not easy for my pov, and of course i will need a apogee meter to compare or calibrate, for my actually its imposible...

...one more link...

...and wilson ...what music for the run run canary forum...

ouuu yeahhh... bump up the volumeee...



....pardon... continue guod... or others .... its nice see you in my disaster thread... curious about multimeter recomendation too or others opinions... fluke its a good multimeter for me too... ...i sold mine... :evil: ...yeah wilson i know ...close my mouth...and keep silence mode... okok

ooopss.... pd. ...keep searching diy dli meters or diy uv meter... maybe im dreaming again...

My "PAR meter" is a photo load cell attached to 1 of the 16 A/D converters of an arduino mega.

Calibration is near impossible, but it can tell me which spot is the brightest.
