Quinled Digiquad V2.r7 and Onboard Temp Sensor

Usermods
1

I have two quinled quad boards and have tried to get the temp sensor to read on them with the following setups:

    • 2 different Quinled ESP32’s with the antenna connector
    • 2 different Quinled ESP32 ABE’s with the network card hat

In all cases i have compiled the latest version 0.13.0-b7 from github on the units and I can see Temperature user mod settings screen, and can select the pin13 for the sensor.

This results in “0 Sensor Error!” message in the info screen.

I thought the code would disable the settings screen if it did not find the sensor during boot, if so then it see the sensor but cannot read the temp from it.

ESP32 has a long standing issue with correct readings of DS18xx sensors. At least with WLED running.
Please use experimental builds from @srg74 which have some slight modifications.
And report back.

Where is the link.

has there been any update on this? I have tried to enable the temperature sensor on my V3 Dig-Quad and all I get is sensor error. I have used the latest .bin file from QuinLED with the temperature sensor enabled.

Follow up with to my previous post, the temperature sensor seems to be working now. I had a look at the board, and it looked like the sensor was bent, so I bent it back to what I thought was the original position. Reconnected and all seems good now.

Would it be possible to have multiple temp sensor ?
Would love to have the temperature of the power supply and the control board and why not also the led strip temperature.

I know there is enough GPIO but can we use them for that ?

These are called a 1-wire sensor, and multiple units can be connected in a serial fashion, each being assigned a unique address. I use them all the time in my home automation system. Search for the Dallas 1-wire data sheet. They are extremely accurate and reliable.

Hi,
Thanks for the information. I try to understand, I have a DS18B20 so I have 3 pin, so i plug the data in parrallel ? and it will just works ?

Hi,

The components need specific attention to connect them in serial. They also need a pull up resistor and a ceramic capacitor to send smooth data. It’s all in the data sheet. Here is a rough description of how I connect them for remote measurements:

Wiring recap with CAT5 cable

  • Pin 1 (GND) → CAT5 Blue/White and Orange/White (both grounds tied together).

  • Pin 2 (DQ / Data) → CAT5 Orange.

  • Pin 3 (VDD / 3.3V) → CAT5 Blue.

  • 100 nF ceramic cap: solder right across Pin 3 (VDD) and Pin 1 (GND).

  • ESP end:

    • 2.2 kΩ resistor between DATA and 3.3 V.

    • 100–220 Ω series resistor inline with DATA right before the ESP pin.\

  • You have the type that goes on a circuit board, but the same resistor/capacitor pair is still needed

ok thank you,
so that’s mean i guess that currently without hardware modification it’s not possible to handle multiple sensor :frowning:

Hi,

That’s correct. However the charm of the Dallas sensor is that once the initial probe is installed, the rest just connect serially. Each sensor has its own address in the form “0x123456789101112’“ and so the next sensor would be assigned “0x12345678101113” or something like that. As I said these are rock steady probes once they are set up.
Good Luck!
