Product Description: Underwater Ultrasonic Sensor for distance measurement

BLJ Ultrasonic waterproof snesor module



BLJ-ME007Y-PWM module provides ultrasonic 30cm-3m of non-contact distance measurement function, range sensor in the sensor output corresponding to the objects in the high pulse width signal. Right picture shows the BLJ-ME007Y-PWM appearance.




Detecting range: 30cm-3m

Best in 30 degree angle

Electronic brick compatible   interface

5VDC power supply

Breadboard friendly

Dual transducer




After power on, the module waiting for the trigger signal. Triggered automatically issued within 8 40kHz cycle level, and to detect the long echo time, and through the corresponding timer output level TTL level PWM pulse width. According to the object at different distances, a corresponding proportion of the output pulse width. MCU can be used to determine the timing of pulses calculated distance. Formula: uS/5.8 = mm, or uS/148 = inches. If the object is not detected, the module output pin pin will output a constant pulse width of about 35MS.

Note: The module detects a minimum distance of 30cm, 30cm inside the object, the signal will be inaccurate.
