NodeMCU-ESP8266 from AI-THINKER not reading waterproof DS18B
Posted: Sat Feb 23, 2019 5:01 pmHi experts!
My NodeMCU-ESP8266 - AI-THINKER can not read waterproof DS18B20 but can read DS18B20 in TO-92 version.
My Fluke reads 3.3 V sensor supply. Have tried different pull-up resistors 4.7 k and lower. All trials in standard connection.
The waterproof sensor can be read by Arduino Uno, not only on 5 V supply but also on 3.3 V supply!
Any idea?
