Waterproof Transducer Ultrasonic sensor small blind arduino replace JSN SR04T

Description

1 transducer 48 KHz
Introduction:
The ultrasonic ranging module adopts the industrial grade 48KHz frequency ultrasonic probe, which has high precision and stable performance, and does not interfere with the ordinary parking radar 40KHz.
It adopts industrial high-performance, high-speed single-chip processor as the processor, and the distance measurement has software correction. This module provides various working modes such as RS232.
The RS232 interface can be directly connected to the serial port of the PC or the terminal of the terminal instrument. The serial port debugging assistant can send the control command on the PC to easily test the module and the receiving distance value. The measurement accuracy is very high ( + 5mm).
Other output interface modes (pulse output, level, PWM output, etc.) can be customized according to your needs!
