SKU: SEN0519
DFRobot URM15 is an ultrasonic ranging sensor with an IP65 waterproof probe, offering 30cm-500cm range (flat wall). It uses RS485 with Modbus-RTU for reliable communication, supports revisable slave addresses/serial parameters (works with industrial controllers). It has temperature compensation (external/onboard) to reduce temp impact, uses a 75KHz 40mm transducer for small angle and high sensitivity.
