Arduino - HC-SR04 Ultrasonic Sensor Distance Module

Quick question:
I have attached the picture, what the input and output should be set at?

After making changes or adding pins, do I need to download the sketch and make your changes into the new uploaded sketch?

Thanks, Aldo

There is no output set up in the code so you only need the input for the moment.

If you are using Ethernet then you can not use some of the pins as they are used for the shield. Pins 12 and 13 are two of them so change the pins in the code to pins 8 and 9 and connect the sensor to them and upload the code again.

You do not need to update the code if you make changes to the plugin config only if you change the code for the API.

For the normal Sketch you do not need to update the board once it is set unless you change the IP config or change it from IP to a com port.

Edit: I need to play with this some more, in the mean time I think I have found the issue with Unknown, I was setting the status to value, I changed it to string and it seem to be working ok. Still not sure if the refresh is right or needs to be adjusted.

Thanks Greig, almost there. Sometime it reads the values like Dim 73% then mostly shows the value Unknown, I think it can not keep up with the value changes.
these are the messages I get in the log

Trust me, I'm reading as much as I can and getting my brain to overload, I saw it in your manual at one point but I recollected it after you told me.

If I would like to integrate the switch into the API. Let me know if I'm doing it incorrectly:

#define inputPin 5
--
pinMode(inputPin, INPUT);
--
SendToHS(2,inputPin);

Then create in the plugin an input pin.

Not sure why but the values given by the sensor are sporadic, anything that we would need to adjust in the code?

I'm also trying to implement the water level switch as part of this implementation, it has been already tested in the normal Arduino code, I would like to implement it into the API, is this the code that I would need to add to the API?

#define inputPin 5
--
pinMode(inputPin, INPUT);
--
SendToHS(2,inputPin);

Then create in the plugin an input pin.

Thanks,
Aldo

Aldo Sorry I missed this post.
Yes this is the code to add to the API but also add a change detection "IF" because this will send the value to HS every time the code loops and this is very fast so will likely crash the plugin.

Thank you Greig.

Reviving this old thread, I'm going to use a similar sensor setup to monitor the water level in a reservoir.

Checking here to see if the code referenced in this thread is still good or does it need to be tweaked\updated? I will also use this waterproof version of the sensor:

Thank you!

Follow-on, there seems to be a Newping library for Arduino that is compatible with the mega and sensor mentioned. Will give this a try
https://bitbucket.org/teckel12/ardui...newping-sketch

Assuming I can load the library\sketch and this should work with Homeseer Arduino?

[enigmatheatre]

I see no reason for this to not work with the Arduino plugin API sketch. Just make sure you do not use delay and only send updates to HS when the value changes. Please post back if you get this working or not and we can help you out if you get stuck.

Greig.

Good deal, I have a mega, ethernet hat and sensor kit on order.

New user on the plugin and Arduino in general, I've been running RaspberryIO with a Pi0W as a remote board that I think has finally bit the dust.


Edit: moved code to current post
