I have purchased an hall effect sensor and display unit from ebay.

The instructions are in chinese and the vendor has been no use at all.

Has any body got a wiring diagram that i could use

There are a few different versions, I am guessing the sensor has three wires brown/blue/black. Brown is positive blue is negative and black is the output, the display will also need the same supply. A picture of what you have will help.
