martin,

I wrote this, because I think that mantouboji has connected badly the sensor.

I use the same hardware configuration for a long time , running very well under kernel 3.x

still have the same problem?

 Yeah, It can't works at all.

I also had problems working, I reloaded armbian with the new kernel, connected sensor and resistance (checking that the circuit is correct) and works continuously for months.
Read my previous posts and connect everything as I did I must work! (from what you posted seems just the sensor that is mounted badly)

I'm sorry if I insist.

In /boot/armbianEnv.txt, along with adding w1-gpio to overlays, did you provided W1 parameters, param_w1_pin and param_w1_pin_int_pullup ?

Are you sure you have the proper pin ?

I'm about to start tinkering with a DS18B20 clone on an Orange Pi Zero running Armbian buster with Linux 5.4.31-sunxi.

I will re-read the whole thread to avoid any obvious mistake.

gounthar,

activate 1wire, edit armbianEnv.txt, connect the sensor (with pull-up resistor) to the pi pins correctly, and it will work everything

@gounthar

 

how i did it with my OPZero:

 

Enable w1-gpio

 

add

param_w1_pin=PA10

to armbianEnv.txt

and connect your DS18B20 like these..

+------------------------------------------------+
| OPi Zero GPIO Pin      |  18B20  | Widerstand  |
|------------------------|---------|-------------|
|Pin 17 3.3V   | braun   |   VCC   |-|4,7kOhm|-¬ |
|Pin 26 1-wire | blau 	 |   Data  |------------ |
|Pin 9  GND    | schwarz |   GND   |			 |
+------------------------------------------------+
 

Its working fine :-)

 

 

macbreaker, beautiful

Thanks a lot, folks, that will help me for sure!

It looks like it has been detected. I now have to find where the information is stored.
I may have found it:

cat /sys/devices/w1_bus_master1/28-3c01a8160ce7/hwmon/hwmon0/temp1_input

Thanks a lot!

i do this:

Thanks. I don't know yet what this output means, but I'll find out.
Anyway, I tried to install RPi-Monitor, but it looks like something failed along the path:

sudo armbianmonitor -r
Installing RPi-Monitor. This can take up to 5 minutes. Be patient pleaseE: Unable to locate package rpimonitor

Now patching RPi-Monitor to deal correctly with H3

gounthar ,

If you intend to use rpi-monitor to control the temperatures of the sensors I recommend you to leave it alone, I use domoticz works well and it's simple, if you need more info open a new post.
