Operating voltage :5V(DC); Electrostatic current: less than 2mA;
Output signal: frequency signal, high level 5 V, low level 0 V

Sensor Angle: no more than 15 degrees

Detection distance :2cm-450cm.
High accuracy: up to 0.3cm

Input trigger signal :10us TTL pulse
Echo signal: Output TTL PWL signal

Definition of pin:
-CC: connects to 5V DC
Triangle (T): Control pins that connect to standard I/O ports
Echo(R): The receiving end is connected to a standard I/O port
GND: Ground

Module working principle:
When the pulse exceeds 10us, the triangle pin is pulled to a high level and the module begins to range.

The module automatically sends eight 40KHz square waves to detect whether a signal is returned.

Note:
Module should be plugged into the circuit before powering on to avoid high levels of misoperation;
if producted, power it again

Connect the GND terminal to the module before connecting the VCC terminal.
