- Solid build precise ultrasonic detection module with extra pins,accurate between 2cm~450cm.
- Durable and easy to set up, requires DC 5V input voltage, quiescent current is less than 2mA.
- Using IO trigger for at least 10us high level signal, effectual angle is 15 degree.
- Automatically send eight “40 kHz “and detect whether there is a pulse signal back.
- If the signal back, through high level ,time of high output IO duration is the time from sending ultrasonic to returning.
