Product features

Use IO port TRIG to trigger ranging. It needs 10 us high level signal at least.
Module can send 8 pro 40 kz square wave automatically, and will test if there is any signal returned.
If there is signal returned, output one high level signal via IO port ECHO. The duration of the high level signal is the time from transmitter to receiving with the ultrasonic.
Testing distance =duration of high level*sound velocity(340m/s) / 2
Static Current(Max) : 2mA ;Electrical Level Output : 5V High; Detection Distance : 2cm-450cm;High Precision: : 2mm

Product description

Module main technical parameters:
Working Voltage : 5V(DC)
Static current: Less than 2mA.
Output signal: Electric frequency signal, high level 5V, low level 0V.
Sensor angle: Not more than 15 degrees.
Detection distance: 2cm-450cm.
High precision: Up to 0.3cm
Input trigger signal: 10us TTL impulse
