Temperature sensor - DS18B20 - Sensors - Arduino Forum

I am having a strange behavior with the temperature sensor DS18B20. When I have two sensors, it works just fine, as expected. It detects both sensors and I can read both temperatures. If I disconnect one sensor, then I detect 0 sensors. The wiring that I have is like this: The pull-up resistance that I am using is: 4.7kΩ. I connected VCC to VIN in the ESP8266. I am pretty sure the issue is electrical not related to programming. In setup I have the following line: Serial.print( sensor
