URM06 - UART Ultrasonic Sensor [Discontinued] Connector_VGA The address pins are tied

The address pins are tied to GND (low) via a 10K resistor so the jumper is used to tie a pin to Vcc (high)

USB to RS422/RS485 converter has many advantages

Includes schematics

PIN10: GND ground

URM06 - UART Ultrasonic Sensor [Discontinued] Connector_VGA The address pins are tiedUltrasonic sensors emit ultrasonic pulses, and by measuring the time of ultrasonic pulse reaches the object and back to the transducer, the distance of sensor from the target object is calculated. They are widely used in detecting displacement, thickness, distance, water level, material level and transparent objects. The URM06 UART Ultrasonic sensor provides very short to long range detection and ranging from 20cm ~ 10m, comes in a compact, robust PVC
