Calling all math majors

I've had good luck using these to house electronics on my bikes. They come in a variety of sizes and are reasonably weatherproof:

I bought a Watt Hour meter,..

I realized that I can also use it to see the current tgat the LED strips are drawing in my grow closet,..

I've got 4 volt/ammeters keeping track of my LED lights,..

They SUCK !!! 😂


There's too many amps going through the crappy little connector and they ended up burnt.
My lights would go dim or bright when I touched the connector.

Two adjacent walls were connected to one power supply and with the other two walls getting more power, the plant started leaning towards the brighter walls. 😂

I ended up soldering wires directly to the circuit board to bypass the connector but never did convert them all, and just deleted them.

Now I use my light meter to measure PAR and a digital IR thermometer gauge to check the LED strip temperature to make sure I don't cook my plant or lights, but I would still prefer to see the current draw.

My strips have a temperature test point on them to check the temperature,..

At first I thought I needed to connect a metal probe to the copper Tc1 test point, but it's just a bare copper spot that gets the hottest.




The HAL sensor ammeter will Work GREAT to check the current going through my LED strips without interfering with the circuit.

I just unscrew a wire, feed it through the sensor then reconnect the wire.

I also found this volt/ammeter with screw terminals, but it also has that stupid built-in shunt thing with all the same shunt issues,..

The screw lugs would be a lot better, but I don't like running all the power through those crappy meters. 😂
