Welcome to tlmaster!
Main: instrumentation, electric tools, hardware, electrical equipment, focus on us for more favorable and new information

This product is easy to use and controls ports above 10 us, and you can wait for the high output of the receiving port.When the timer value of the port becomes lower, the timer output can be opened, which is the time within the range of calculated distances.The performance of the module is stable and accurate distance measurement.And srf 05, srf 02 ultrasonic distance measurement module.Module precision, blind spot (2cm) is super - close, distance measurement is stable.
Characteristics:
The performance of the module is stable and accurate distance measurement.
Module precision is high, blind spot (2 cm) is super - close.
High accuracy can reach 0.3 cm, detection range is 2 cm - 450 cm, induction angle does not exceed 15 degrees.
The module provides range-measuring programs: c51, pic18f877, ultrasonic lcd1602, ultrasonic lcd12864, digital tube display, serial display, distance-measuring reference program.
Simple and easy to use, io trigger range at least 10 u.s. high signal.
The module automatically sends eight 40 khz square waves to detect whether the signal returns.
The signal returns to a high io output, and the ultrasonic time between launch and return is longer.
