Maybe you have to do some (internet) research on how the screens of smartphones or tablets work. something like this. Ok it's a little bit over the edge for a Arduino, but it gives some direction I hope.

What do you mean by a HE? Human Engineering? Heavy equipment? High End (system)? Happy Ending ?

This is probably a module that uses CAN-bus as a bus interface. CAN-bus is used in automotive te reduce the number of wires in order to minimise cost. Other busses, used in industry are MODBUS, profibus, etc.

In a way you could see mySensors as a bus system as well as it is wireless Could be very beneficial for your challenge: each machine one or more sensor-node(s) - depends on the number of wires you'd like to monitor and the level of multiplexing you'd allow - and a gateway that is connected to a dedicated controller. This controller (I think not one of the controllers as used in the mySensors community) is used to translate the messages to instructions where to repair the yarns.

First thing to do for you is understand your real problem (yarns are breaking) and how you'd like to interact on this.
I think it's good to re-read the remarks @Bogus-Exception made! I strongly suggest you to read that again!

Hi Reshma,

I googled your question ("connect multiple hall sensor to digital") and guess what happened...

this was the first hit I got from google

It may not be exactly what you're looking at, but what I try to explain here is that using google for this may be more helpful than posting it in this forum as I think your question is more related to using arduino in general.

Consider the use of resQ tape. Not sure if this is available world-wide, but the use of it is very versatile.

I've used heat shrink with and without the glue layer inside. Works for some time, but water gets in. Only the resQ tape has proven to keep the joints (cable entries of the connectors) watertight!

above link is an example of a sensor which could be used. Not sure what the level change will be, but the "new law" as you refer to will tell you what accuracy is needed. This sounds to me as a perfect example of a LoRa sensor.
The sensor goes in the bore hole (same as the manual cord measuremens) and stays there. The electronics (4-20 mA preferrably as 1000 ft is quite a distance) can remain at ground level.

If you have any idea what the change of level is in the well, you can easily find the range for the sensor.

Have a look at freescale sensors. i.e. MXP-type sensors. You could ask for samples (they will provide up to 5 pcs. for free). Cost around $15 pcs. normally.

You'd mount such a sensor on top of a riser (air-tight) and when the (sewage) water rises, the air-pocket is compressed proportionally. This is how I measure the ground-water level at my location and it helps me to keep my basement free of water. Works flawlessly!

@moparjay
have you thought about using a jfet?

see here for a google search

@sirzlimz
Nothing wrong with the wiring. As @zboblamont already stated you've used the parasitic mode.
All my DS18B20's are connected that way (using pro-mini's).

Any code available?

@mfalkvidd

and a simple 'trick' to allow higher currents if necessary:

A network cable has 8 leads in it. Any spare pair of leads not used for something else (e.g. data....) can be used to increase the current strength of the 5V and return (GND) line.
