Hello, I plan to position two ultrasonic distance sensors(4 pin type, like the HC-SR04) in front of each other at a known distance, send a pulse from both sensors at the exact same time and measure the time (Or distance and divide by the speed of sound) it took for the pulse to get to the other sensor. Is it possible? Would the sensors be able to pick the pulse from the sensor in front of them? (Sensor A picks sensor B's pulse, and sensor B picks sensor A's pulse) If not, would it be possible to use one sensor as just a transmitter and another as just a receiver?
The idea behind this is to build an ultrasonic anemometer (Measure wind speed) using four sensors.
