Issues dallas sensor and sketch

[pkriek]

Hi

I have made multiple senors using the sketechs and fantastic site. I only have issues with the Dallas tempertatue sensors to get them working.

I attached 2 dallas sensors to an arduino pro mini 3.3 v. I used the sketch that is provided on the site.
prblem that it works sometimes for 1 sensors, some times 2. So I replaced both sesnors, and now I cant get an reading at al.

Thru the serial monitor I see most of the times 1 sensors, it alsoshows up in domoticz, but is not reporting. So it seems very intermittenmd working.

Can it be the pullup resistor? I use the 3.3 v from the arduino itself.

thanks for helping

Have you restore the EERPOM memory ?

Hi

With a new one,not soldered, but attached to teh clamps, it is working. This gives two posible exolanations:

• the dalls sensor breaks easilly when soldered, can not have high temps.
• I had a very bad packages . 3 from 10 pieces working.

Have similar issue while connect 1-wire sensors to pins 4 (power) and 5 (data) for low energy sensor.

Looks like at least pin 5 used internally (as LED ?) by MySensors and broke 1-wire i/o.

After moving 1-wire "data" pin to "A1" and hardwire "power" pin to "VCC" I have no issues with DS18B20. But about 3.5uA per sensor more in sleep (11-12uA instead of 4.7).

BTW: still have issue with node registration and/or other connection issues - after approx. 2 days node whan't to send data to gateway... Will debug later.
