Introduction
URM37 V4.0 Ultrasonic Sensor uses an industrial level AVR processor as the main processing unit.
It comes with a temperature correction which is very unique in its class. URM37 V3.2 (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
