xzkeee posted a topic in General DiscussionI 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
