ESP8266 Community Forum

- Tue Jun 16, 2015 1:27 am #20566 Good day to all of you in the forum.
I am using the ESP8266 and one ds18b20 sensor and I do read the temperature on my mobile phone.
Thanks to this forum for the assistance provided.
>> I would like to connect more than one ( let me say five ) ds18b20 sensors to my ESP_01 and reading the temperature on the mobile phone.
I understand that the sensor is ONE_WIRE capable and so one pin should be enough for the interface.
I would appreciate very much to have some help in writing the program.
At the moment I am running LUA nodemcu as firmware.
Thanks for helping.

- Wed Jun 17, 2015 2:25 am #20661 I don't know LUA but its certainly possible to have multiple DS18B20s on a single bus and straight forward enough to read from each with Arduino code and should work fine on an ESP. If you google there are lots of examples, this looks like a good write up - https://arduino-info.wikispaces.com/Bri ... 18B20#mult

I will like to interface the sensors to the ESP_01 without any additional MCU in between.
Any assistance is appreciated.
