HC-SR04 feedback #17

Closed boverby closed 6 years ago

boverby commented 6 years ago

Thank you for adding support for HC-SR04.

I have used it this morning on a christmas tree water level sensor. The only change I needed to make was upping the MAX_DEVIATION_BETWEEN_MEASURES from 0.1 to 75.00. The original value left me wondering if the sensor was fried, but enabling the "HS-SR04 In Duration:" debug showed that it was indeed changing with new depths. The 0.1 value for MAX_DEVIATION_BETWEEN_MEASURES was acting as an intended damping factor , but was so slow that I got confused. I know that the sensor is "noisy" so I was thinking about taking the 10 samples and getting the median value instead.

No changes requested, just feedback that might help another user.
Thanks again

Hi @boverby,

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 6 years ago

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.

junk-barkass commented 6 years ago

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...

stefanbode commented 6 years ago

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.

junk-barkass commented 6 years ago

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

stefanbode commented 6 years ago

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

junk-barkass commented 6 years ago

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 6 years ago

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 6 years ago

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.

At the moment when the logg was taken the sensor were disconnected.

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

Great!!!

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