ULTRA SONIC SENSOR MODULE

Description

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 2mm,Input trigger signal : 10us TTL impulse , Echo signal : output TTL PWL signal
NOTE : The module has a blind spot of 2cm(very near). So obstacle held too closely will not be detected.
