Hi, could you please clarify the question a little bit more? Do you want to say that you need to send an Ultrasonic sensor's(like HCSR-04) output from one Arduino to another? Do you want to send this your data using wifi?

I was a little fuzzy too. Title says WiFi, so if you want to communicate between two Uno's, you need an ESP8266 on both ends. If you want to communicate by ultrasonics (sounds like a cool science project) then you don't need any ESPs. Though if you want to use WiFi, I'm not sure what the Uno's are for. The processor on the ESP is 10x the Uno. Just hang the ultrasonic sensor off the ESP and call it good. You can almost buy 10 ESP's for the price of one Uno.
But... you need a special HC-SR04P to handle 3.3V logic. Although, I just stumbled across this hack to make a regular HC-SR04 work. Have to give that a try.
