ESP8266 - temperature sensor troubleshooting

That interface board already has a 4.7K pull-up resistor.

You don’t need the extra one in the screw terminals. It won’t be the cause of your issue but you can remove it for simplicity.

EDIT: actually it might be a problem. If that colour code is yellow - purple - gold - gold then it is a 4.7 OHM resistor (not K Ohm). If it is yellow - purple - brown - gold then it is a 470 Ohm resistor.

Both are very low values that the sensor may have trouble pulling to ground.

Remove the resistor from the screw terminals.
