TLE4905L

Hello,

How to connect 4905 hall sensor on digital pin? What do i need for wiring that and how?

Thanks,
teo

Do you have a link to the datasheet?

Here it is Infineon 1-tle4905l datasheet pdf

Pin Vs to +5V
Pin Gnd to arduino ground
Pin Q to any arduino digital input expect 0 & 1

Enable the internal pull up resistor, by doing a digitalWrite HIGH to the input pin you use, in the setup()

Then read it like the button sketch.

Thanks, this was much easier than I thought.. Tested, and working great of course..

I don t want to open new topic, but i have more questions..

How to connect LM35DZ http://www.ti.com/lit/ds/symlink/lm35.pdf

And how to connect LM335Z http://www.ti.com/lit/ds/symlink/lm135.pdf

Both connecting to analog...

What is the difference between those two? The difference that I think I see is that for the 335 I only need two wires, and for the 35, I need three, and both need to use some resistance to the connection... Or I am wrong?

Again thanks for the prompt answer!

How to connect LM35DZ

Figure 1 on page 2 of the data sheet with the output feeding directly into one of the analogue inputs.

And how to connect LM335Z

Basic sensor on page 6 of the data sheet with the output feeding directly into one of the analogue inputs.

What is the difference between those two?

Well it is all in the data sheet, but basically the LM135 gives you one degree accuracy and the LM35 gives you half a degree accuracy.
