Will anyone buy a homemade 150$ Quantum Par Meter?

[xzkeee]

I just started a reef tank recently, made a DIY Led light.
Because my light is DIY, I have no idea how much par I have.
Apogee par meter is way too expensive for me. I am not happy about the price. So I start to look for a way to make it myself.
Every par meter on the market is so expensive
there is a very cheap way(use TCS34725) but requires a par meter to celebrate.
Then I found a par sensor, advertise to have +-1% accuracy,0-2600 mol/s range,400-700nm Spectral Measurement Range.
At ~60$ price. This is an acceptable price for me. Already order one and arrive tomorrow.

Then I am thinking of design a case for this, use 3d print case, OLED screen,18650 battery, Arduino, or stm32 chip.
Will anyone want this? Thinking of selling this for around 150$.
Please let me know what you think about this thing.

By the way, if you want to save even more money, you can buy this sensor from the seller. Not sure if they ship overseas.

Here are pics of the led light I made

Well, when you get it completed post some more details...

Little update.
I got the sensor and write the code to make a little demo.

here is a video for this


Works quite well, respond like a par meter. No idea how accurate it is, but good enough for me. Know a rough idea of how much par I got.
Since not many people interest in this, I gonna end this project here.
It works for me and no need for a case for myself.

If someone looking for a cheap way to get par, this way is a good option!

Isnt the Apogee 120 available anymore? That was only $150 when I bought mine, and Apogee lists correction factors for use with LEDs. That with a $20 multimeter from Home Depot = a PAR meter that matches the readings from the expensive high end units, with appropriate calculations.

Things is, I dont see it available on their site right now.

They don't sell 150$ par meter anymore, the cheapest one is 375$ I can find on amazon. I guess they want more profit so stop making cheaper models.

You can (still) buy just the Sensor :

Apogee SQ-120 Quantum Sensor

.

And combine it with a multimeter.
It has the added benefit of beeing waterproof.

USB Smart Quantum SQ-420X PAR Sensor

PAR (photosynthetic active radiation) is the easiest way to measure the available light for corals consume and use for photosynthesis. With LED lights giving more and more control to the consumer the best thing is a PAR meter that is affordable and simple to use. With PAR readings you can...

Hook this up to a USB port on laptop or tower and you're good to go.
