   1.Working Voltage : 5V(DC)

   2.Static current: Less than 2mA.

   3.Output signal: Electric frequency signal, high level 5V, low level 0V.

   4.Sensor angle: Not more than 15 degrees.

   5.Detection distance: 2cm-450cm.

   6.High precision: Up to 0.3cm

   7.Input trigger signal: 10us TTL impulse

   8.Echo signal : output TTL PWL signal

   Mode of connection:





   Use method:

   Supply module with 5V, the output will be 5V while obstacle in range, or 0V if not.The out pin
