US-100 is the perfect ultrasonic distance sensor for all ESP8266 modules. Mainly for two reasons. It runs on 3.3V and it can feed you measurement readings via UART or Serial communication. And also, it measures temperature!

It works excellent with ESP-01, ESP-12E, ESP-12F, ESP-12S, ESP-07, Node-MCU, Wemos and all other ESP8266.

If you are connecting it to a Node-MCU, Wemos or similar you have a 5V pin and can use it. But you are using the ESP-01 or ESP-07 or ESP-12 on a PCB you might not have 5V available. So then the US-100 will fit you project perfectly.
