Hey,
I want to do a project where I connect this sensor PN7001 - Drucksensor mit Display - ifm or a similar pressure or temperature sensor to an arduino. Firstly, is this possible? If so, how do I connect it?
I also want the values read to be viewed remotely from an android device using a Phpoc shield or some other Wifi module.
I appreciate any answers or better ideas to do it.
Thanks.
Laura
The sensor appears to have 2 digital outputs and an IO-Link serial interface
From their web site :
output Switching signal; IO-Link; (Configurable)
Number of digital outputs 2
output function Normally open / normally closed; (Programmable)
The digital pins and serial interface could be connected to an Arduino but you will need to know what the IO-Link provides and in what format.
What exactly do you want to use the sensor for ?
Hey Bob
The project is for a CNC machine since the sensor is inside the machine and cannot be seen during runtime. I would like to connect a module between the cable and the sensor so that the values can be seen remotely from a device. Comprende?
Comprende?
Yes, but do you have any details of the data and format of that data provided by IO-Link ? Without it you will get nowhere ?
To start with, what baud rate does it run at ?
Okay, I understand what you are asking for.
the transfer type is COM2 with baud rate of 38400 bps
minimum process cycle speed is 2.3ms
process data analog is 1
process data binary is 2
Programming of the output function
----------OUT1----------
Hno = hysteresis / normally open
Hnc = hysteresis / normally closed
Fno = window function / normally
open
Fnc = window function / normally
closed
----------OUT2----------
Hno = hysteresis / normally open
Hnc = hysteresis / normally closed
Fno = window function / normally
open
Fnc = window function / normally
closed
dESI = diagnostic function (normally
closed)
Have you got any more details on programming the device and the format of the data that it outputs ?
What happens if you write a sketch that uses SoftSerial to communicate with the sensor at 38400 baud and print what you receive to the Serial monitor ?
Hey I'm sorry. I'm pretty new to this as you can see. I'm not even sure how to connect it to an arduino board let alone program it. I don't know the answer to your question. How do I find it?
Thanks
Start with the basics.
If you have an Arduino then try out the examples in the IDE to get a feel of how to program it.
If you don't yet have an Arduino then I suggest that you get a Uno as your first board.
Do you have any programming or electronics experience ?
Yeah I know to code basics in C++ and python but haven't really used arduino much. I'll look into it. Thanks. If you can tell me what steps I should take for this project, that would be nice.
Thanks
The Arduino is programmed in C++ so you will have a good start.
As for connecting the pressure sensor to the Arduino, do you know what signal levels the sensor outputs ? Is is TTL (5V) or RS232 (-12V to 12V) ? If it is the latter then you will need a to convert it to TTL in order that the Arduino can read it. If it is TTL then I will give you a small sketch to test it out.
Yes, it's TTL.
LauraDerolez:
Yes, it's TTL.
That's good news.
Which Arduino board have you got ?
Connect the serial output from the sensor to pins 2 and 3 of the Arduino board. Tx from the sensor to pin 2, Rx from the sensor to pin 3.
Copy this program into the IDE and upload it
#include <SoftwareSerial.h> //software UART library
SoftwareSerial pSensor(2, 3); //create an instance of SS named pSensor. Pin 2 is Rx, pin 3 is Tx
void setup()
{
Serial.begin(115200); //start hardware serial interface
pSensor.begin(38400); //start the sensor interface
}
void loop()
{
if (pSensor.available()) //if data is available from the sensor
{
Serial.print(pSensor.read()); //read data from sensor and print it to Serial monitor
}
}
Open the Serial monitor in the IDE and set the baud rate to 115200
Do you see anything in the monitor window ?
It is quite possible that you won't as more setup of the sensor is likely to be needed, but it is worth a try.
