الوصف
a common type of ultrasonic sensor transceiver, typically sold as a matched pair (T=Transmitter, R=Receiver), that operates at a nominal frequency of 40kHz, featuring a 16mm diameter, used for non-contact distance measurement, robotics, and liquid level sensing, known for its compact size, high sensitivity, and compatibility with microcontrollers like Arduino after adding external circuitry
