It has rich interface and offers various output: analog output, switch, serial \n(TTL and RS232 level optional), PWM and so on. With analog mode, the sensor outputs voltage which is proportional with distance, it can be connected\nto Arduino, Raspberry Pi and LattePanda(windows 10 development board). The module can be used to measure the rotation angle of the servo. Connected with an\nexternal servo, it changes into a spatial ultrasonic scanner. URM37 has been on the market for many years and plays an important role in various fields, and\nwe are constantly optimizing and improving it. The mechanical size, pin interface and communication commands of this version（V5.0）are compatible with older versions.\nBased on the old version, the following improvements have been made:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe range has been increased from 5~500cm to 2~800cm\u003c\/li\u003e\n\u003cli\u003eThe ranging performance is very stable at the voltage range of 3.3V~5.5V.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\nURM37 V5.0 Ultrasonic sensor, the current version has better intelligence capabilities, meanwhile, mechanical dimensions and pin interface and communication commands are compatible with V4.0: \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOut of the use of a better ranging method, the measurement distance is further and more stable. if there is a need for customization, please contact the company.\u003c\/li\u003e\n\u003cli\u003eThe module uses RS232 serial port for higher reliability, and the data can be collected through the computer serial port, which is very convenient to write communication programs.\u003c\/li\u003e\n\u003cli\u003eSerial level selected from the skipped stitches to button, user can easily select RS232 or TTL-level output level output by pressing the settings( after reboot ).\u003c\/li\u003e\n\u003cli\u003eThe measured distance can be output via PWM, which eases the use process of the module.\u003c\/li\u003e\n\u003cli\u003ePre-set a comparative value for the module, under the mode of automatic measurement, if the measured distance value is smaller than the pre-set value, the pin COMP\/Trig will output a low level.
