Arduino PHORPDuino Shield

Posted Mon, 11/30/2009 - 16:52 by andrew1056

The Arduino BNC sensor shield is designed for very high impedance low voltage sensors (pH, ORP etc.). It has 2 BNC connectors as well as a variable resistor to control the gain.

Overview

 

Demo

Features:

  • 1 PH BNC Connector
  • 1 ORP BNC Connector
  • Variable resistor to control gain
  • Stackable

Currently, I've only designed 2 versions of this shield. One is for analog pins 0 and 1 and the other is for analog pins 2 and 3. Since I2C is nice I'll also be adding an I2C model which would allow you to have up to 10(?) BNC sensors hooked up (analog and I2C).

These schematics use analog pins 0 and 1; however, it can be changed quite easily by moving the nets to different pins.

Thanks for giving us the PCB and schematics. Can you please explain, in which software are you making it? I can open the PCB in Altium Editor, but cannot open the sch file. Any clues?

Thank you in advance

Hi,

The link to the kit version of the board gives a permission error.

Sorry about that! I've not gotten everything up and configured yet. I'll have it done tomorrow (29th).

Hey. Very interesting

Hey.

Very interesting project. Are you planing to integrate conductivity sensor for meassuring quality of RO water too?

Can you share the shematics of this shield?

Best regards

Schematics are up :-). I am

Schematics are up :-). I am planning on incorporating a conductivity sensor as soon as we've got the code done for these shields.

Hi Andrew. Tnx for the pcb. I

Hi Andrew.

Tnx for the pcb. I can open it, but not the shm file. I am using Altium designer. Can you check your zip file, if there is some kind of errror?

Tnx in advance
