RF Receiver Module 433MHz 433.92MHz RX217 RX500 with antenna 102 1nf 50V 0805 SMD Capacitor GND and the middle pin

GND and the middle pin indicates +5 V

No of Output 04 No

As the propagation speed of the Ultrasonic wave (330 m/s in room condition) and time taken by the wave is known

gets connected to the input 12VDC supply to power the module

Rectifier diode
