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

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.

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