Separating them allows for through-beam detection and eliminates the dead zone present in single-unit sensors, making them ideal for precise distance and flow measurement applications.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Are these ultrasonic probes compatible with Arduino or Raspberry Pi?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. These 40KHz waterproof ultrasonic transducers are compatible with standard ultrasonic driver circuits and can be interfaced with microcontrollers such as Arduino and Raspberry Pi using appropriate driver boards or signal-conditioning circuits. Always verify the voltage and signal requirements of your specific driver board.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Which diameter size should I choose — 10mm, 12mm, or 16mm?\u003c\/h4\u003e\n\u003cp\u003eA: The choice depends on your mounting constraints and application. \u003cstrong\u003e16mm probes\u003c\/strong\u003e generally offer higher sensitivity and output power, making them suitable for longer-range or underwater use. \u003cstrong\u003e12mm and 10mm probes\u003c\/strong\u003e are more compact, ideal for tight-fit installations or applications with limited mounting space. All three diameters operate at 40KHz.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can these probes be fully submerged in water?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The probes feature a fully sealed, waterproof housing specifically designed to function reliably in wet, humid, or submerged environments, making them well-suited for liquid level sensing, flow metering, and similar water-contact applications.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is the difference between the transmitter and receiver in a split-type ultrasonic probe?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"In a split-type configuration, the transmitter probe emits the 40KHz ultrasonic pulse, while the receiver probe detects the echo or the direct signal from the transmitter.
