The board has two supply pins (VCC, GND) and two lines for measuring the distance. A high signal on the connection marked "Trig" triggers a measurement process and sends a 40 kHz pulse. After the module has received the signal again, depending on the distance, a high level for the time t is output at the connection "Echo".
The duration of the level is proportional to the distance. The distance is calculated as follows: Distance in m = t in s. Sound speed (approx.
340 m/s) / 2. The sensor comes with the matching bracket. Please note that no screws are included.
Technical data: Input Voltage: 5V Distance range: approx. 2 cm to 300 cm. Measuring angle: 15 degrees.
Dimensions: 45.5 mm x 20 mm x 18 mm
