hall sensor module

Other Hardware Sensors

Hello!
I have bought the Hall Sensor Module (Tinkerkit), but i would like to know if it was possible to connect it to an Arduino Uno without the TinkerKit Sensor Shield? There are 4 connectors: + , - , PWR, OUTPUT
Thank you & sorry for my english which is not perfect

Up! please

Can you provide a link to the sensor?
It should be fine if the sensor is a 5V one, if it is not then you will have to connect the + to the 3V3 otherwise just connect it up directly. Is it an analogue sensor or a digital one?

And the datasheet: http://docs-europe.electrocomponents.com/webdocs/10c6/0900766b810c6bec.pdf

It seems to be digital

Thanks for your answer

It seems to be digital

But the data sheet says:-

you can see values between 0 (no presence) and 1023 (presence detected).

So that means it is an analogue sensor.

You said:-

There are 4 connectors: + , - , PWR, OUTPUT

But the data sheet shows only 3 connections.
Connect the + to +5V the - to the ground and the middle connector to one of the analogue inputs.

Then write a sketch that reads the sensor and prints out the result.

One thing puzzles me, the data sheet says :-

This module outputs 5v when a magnetic field (e.g. a human body) is close to the sensor, and roughly 0v when there is nothing nearby.

The human body does not contain a magnetic field so it will not detect one. However if you hold a permanent magnet close to the sensor you should see the reading change.

"Connect the + to +5V the - to the ground and the middle connector to one of the analogue inputs.

Before see your answer, i did that and it worked!

"The human body does not contain a magnetic field so it will not detect one. However if you hold a permanent magnet close to the sensor you should see the reading change"
I used neodium magnets and it works perfectly, but as you say, it didn't detect human body.

Thanks again, have a nice day
