Photone phone app vs a couple different par meters

[bk-og]

So a friend asked me to compare my par meters to the photon phone app to see if I can get proper numbers for him. I will be doing it this weekend at some point

I have a pulse pro, which I’ve ran next to the apogee mq500 and I have a photobio

I’ll post pics and result here over the next day or 2

Nice, I’m interested in seeing this.

Nice, I’m interested in seeing this.

Just spent $8.99 on the fucking app after the $1k I’ve already spent on the photobio and pulse pro.

That made me cringe lol

 

[Brettman]

That’s hilarious. How come you have/need two par metres??

Well the pulse pro is my environmental gear, which also has a par sensor. And the photobio is just a handheld sensor

I’m still pretty chaffed at that $8.99. I could’ve had a nice breakfast with that. Now I get buttered toast.

 

[bk-og]

What a waste of money that was. Just did a real quick test on all 3 and the app is out to fucking lunch

Ill get them all perfectly level and same height and re test them here shortly

As my tests before the pulse is within 35ppfd as the photobio , but the app is out by 155ppfd

So it’s off by like 25% lmao Was it high or low.

Pictures are worth 1000 words I thought

I think the app notes mention that it can be off from the start and recommends calibrating it against a higher end meter.

Edit: I take that back...It says it has been calibrated against each iPhone model but it does let you calibrate it if needed.

App is 810ppfd, photobio 655ppfd, pulse 600ppfd

 

[Brettman]

I meant the Phone App. Or is it in the picture ?

 

[Brettman]

LMAO. I’m going to do the app again tonight when I get home. I don’t think I ever did it with my Mars light.

 

[Brettman]

I remember thinking “damn these cheap Amazon panels rock” when I first used that app.

You ever try taking a picture of a phone screen under intense lights lol

This would explain why lol

Oh holy shit it is on your phone screen.

 

[bk-og]

Oh holy shit it is on your phone screen.

Where else would it have been?

 

[bk-og]

Ok got everything nice and level

photon app reading 808ppfd

photobio reading 694ppfd

pulse pro reading 701ppfd

 

[Brettman]

O

Where else would it have been?

No where, I’m on my drill with sunglssses on and couldn’t see it, fumbling my phone with numb fingers in -24c weather doesn’t help either lol.
