URM37 V4.0 Ultrasonic Sensor

INTRODUCTION

URM37 V4.0 Ultrasonic Sensor comes with a temperature correction which is a very unique feature at this level. URM37 V4.0 (last version) has already been a very good realization of ultrasonic switch and serial (TTL and RS232 level optional), pulse output function, the module can also control a servo rotation to realize a spatial ultrasound scanner. On this basis we have to upgrade the function.

URM37 V4.0, the current version has better intelligence capabilities, meanwhile, mechanical dimensions and pin interface and communication commands are compatible with V3.2, V3.2 has been reversed based on the following changes:
 

    Serial 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)
    Modified the algorithm, so dead zone was reduced and enhance accuracy
    Analog voltage output, voltage and the measured distance is proportional
    Wide voltage support +3.3V-5.0V
    Power reverse protection
    Automatic measurement of time interval can be modified
    Modify a servo controlled angle of 0-180, compatible with the most of the servos on the market
    Measuring time is 100ms
