Connecting this ESP3266 to a temperature sensor is easy. All you need to do is a datasheet.
We will use DS18b20 temperature sensor. There are 3 pins for this sensor which are GND (Ground), VCC (Voltage Common Collector), and SIG (Signal).
How we connect the sensor to ESP3266:
GND (Red): To "G" pin of ESP3266
VCC (Green): to 3V pin of ESP3266
SIG (Yellow): to D4 pin of ESP3266
Oh, don't forget a resistor (330 ohms) between a 3V pin and D4 pin.
