how does water level detector work
a 400 ohms relay can not be driven by water resistance.waterresistance is above several kilo ohms. so you need to make a circuit like current booster, level sensor or buy a ready-made a controller called "sivi seviye rolesi"....
Yes Iam tring to get a substitute but for an unknown core.Saturation flux is too what I am really worriying most about.For instance difference is only 30 mT between 3c92 and 3c90.I am keeping try..
At my first try i increased air gap to about 0.5 mm just for to make AC current of the input with no load same as the original.The circuit worked well up to 110 A DC output current without air cooling!!After that 30 USD is gone...Original core had no gap.Switching frequency is 100 KHz.Topology...
Actually, the problem is whether sensing air humidity is the same as sensing the proportion of the water in sand.
If I penetrate a probe with a capacitive humidity sensor on the tip in sand , would I have measured humidity of sand?
Or what I am trying to do is measure volumetric water content...
Problem Set
Does anybody know where i can find the solution to the problem below?
İt will be a realistic conlusion of all lecture notes , application notes etc. for me...
https://ece.colorado.edu/~ecen5817/hw/hw11/hw11.pdf
I dont think there is any diffrence among tuners.Signal inside them is always analog.But the way you demodulate to get the data may differ..
So U can use it.
Converting Device Models
As i can see there is no global standart of the electronic device models.
Does anyone know a program or a way to convert models into another modelling language like spice, vhdl, saber?
proteus h-bridge
Two optocouplers one for the route of SW1 and the other for SW2.
outputs of the coupler will show the current direction... leds may need current shunt in paralel.
