HC-SR04 feedback,about stefanbode/sonoff-tasmota

stefanbode commented on July 20, 2024

yes the noise is quite a pain with the SR04. I already do some compensation in the code. I found out that better than the median/average is to work on the maximum. To don't wast much time I just do 10 loops each measurement. Anyhow also this method does not create good sensor out of a bad one. Therefore introduced the damping factor. this is the maximum change between two measurements between to probes.

Hi.
I'm trying to use your code with a regular son off basic. no need for deep sleep how do i disable it? I just need it to talk to my SR04. I red the above and maybe this link will help you to get better reading for the SR04. https://www.youtube.com/watch?v=6F1B_N6LuKw
Best Regards Magnus

stefanbode commented on July 20, 2024

Thanks Magnus, I will give it a try. Maybe it is because of the 3.7V power and startup from Deepsleep that produce the headache. If you do not set deepsleep it should be 0 BY DEFAULT , that means OFF.

Thanks for quick reply. I'm not a programmer myself but i think it was a very good video.
I ran your code on nodemcu and it worked fine no deepsleep. But on Sonoff it deepsleep even if it's 0.
My problem is not the SR04 sensor yet...

Really strange. I’m on holiday. Therefore a bit difficult to test. There should be no difference. Anyhow. What deepsleep ist reporter in the STATUS Message? You can easily override by sending a deepsleep 0. I also have several sonoff without active deepsleep running fine.

Hello. Enjoy your holiday! I’ve set deep sleep to 0 but it seems not to listen to it. Yes it’s very strange indeed. When are you back home? We can talk more then. Or just send me an email. We can discuss more then. //Magnus

Can you send the log messages during startup? Seriallog 4 should be sufficient. If it uses deepsleep you should see the corresponding messages here.

Hello.
It writes as you can see deep sleep 0, but it is so sleepy... and after a while it restart by itself.

This has nothing to do with deepsleep. This is just the normal behavior after getting a restart command. But I assume you did not type it in. It just appear. Do you have a saved command in your mqtt server? One idea. I can say for sure that from somewhere there is. ‚Restart 1‘ coming.

stefanbode commented on July 20, 2024

Have you switched your trigger an echo pin? I just see the timeout and a measure of 0. this only happens if not connected or wires are wrong

junk-barkass commented on July 20, 2024

Hi. Oh.. Yes you are so right. My server checks connection with all my son off devices and if it’s not responding to a ping then it will send restart. So YES you are so right on. Bu why isn’t it responding to ping as all the other? check the ping time very long time for roundtrip. //Magnus

Is it possible that if no sensor/something not correct will take all time from 8266 and therefore not responding to all my ping:s?

Yes right. If the sensor does not answer, it freezes the ESP for other things. I can reduce the issue a bit , but not general avoid. As soon as there is a device connected everything should be fine.

Aha!!! That’s a fully answer to my problem. Then I know that and can focus on the sensor communication. Thank’s a lot. //Magnus

Added check and support, if SR04 is not connected to avoid the freeze. Will be updated with 5.11 version

The sr04 reading is now quite stable and values fit most of the time. No more changes planned for the distance sensor.
