WQ sensors wouldn't enable

[juan.quinteromarin]

Hi all,

I have a short question in case someone has experienced this before. I am trying to calibrate a WQ kit however, I’m getting this message for each one of the probes: Temperature sensor is disabled!!!

I have tried to enable the sensors with the command sensor temperature -enable, and many other variations, but it’s not working.

Can someone please let me know if I am using the wrong command? is there anything else I can do from the shell - not involving checking the electronics/driver?

Thanks, I really appreciate any feedback.

Hi @juan.quinteromarin !

Have you seen this post? No sensors being recognised

Hi Óscar,

Thanks for your response. I am struggling to find out what are the correct files for the Water Quality station. Some minutes ago I checked through the shell, and the kit had 0.98 for both SAM and ESP. I just updated the ESP, and now when I check in Arduino, it says “ESP version: not synced”, so I think I just made it worse. All sensors continue to be disabled.

I used the version from the screenshot below.

Can I confirm what the current SAM and ESP firmware versions are that I should use for this WQ (SCK 36DB)

Thanks for your support
Juan

Hi @juan.quinteromarin,

For the SAM firmware, you shoould use SAM_firmware_sck_water.uf2. Once you have updated the SAM, you can then update the ESP with ESP_firmware.bin (for instance, with the phone method).

Let me know if it works!

Thanks Óscar! I will try it this week and let you know if the sensors get enabled

Thanks Óscar,
I’ve done the updates, and something improved since now I can monitor Temperature - before, all the sensors were coming up as disabled. After updating using the files you’ve suggested, SAM version is 0.9.10-9256d97-master-sck_water and ESP is 0.9.9-9256d97-master, is this correct? thanks!

However, when I tried to monitor data with the other probes, it didn’t work, and we’re getting the messages attached below. I’ve also checked the sensor status (see screenshot), and they seem to be disabled.

Do you think there’s anything else I can try from the shell, or is it a problem with the drivers? The sensor is new (hasn’t been installed before), so I didn’t think it was that.

Thanks again for your kind assistance.

Hi Juan

What happens if you type i2c on the shell?

Hi Oscar.
Thanks. I typed i2c and this happened:

16:18:32.300 → SCK > i2c
16:18:38.397 → Searching for devices on internal I2C bus…
16:18:38.397 → I2C device found at address 0x6b!!

16:18:38.443 → Found 1 devices
16:18:38.443 → SCK >

If the firmware (SAM version is 0.9.10-9256d97-master-sck_water and ESP is 0.9.9-9256d97-master) is okay, may this be a problem with the hardware?

Thanks

Hi Juan,

It seems that the drivers are not recognized by the kit. This could be for various reasons. Are you using the old version of the station with the “Tentacle T3” drivers? Like below?

Or this one (V2)?

In the first one (Tentacle), the drivers for all sensors except Temperature work at 5V. There There is a cable powering the tentacle board on the bottom of the boards, with a green PCB that may be simply disconnected. The photo below is not “entirely accurate” for those versions, but the arrow points at where the board would be.

That design was significantly improved on the second version, and no additional cables are necessary.

Hi Óscar,

Thanks for your prompt reply, and apologies for not updating you sooner. I only returned to the Lab today to test your recommendation.

This worked perfectly I removed the components with a screwdriver and noticed some cables inside, where the PCB you’ve mentioned is located, were not plugged correctly. I’ve plugged everything back in and now I can see all the sensors working through the shell.

Thanks for your patience. I think we can consider this case as solved.

All the best
Juan
