The HC-SR04 has bare piezo elements that will fail if wet. The JSN-SR04T also has better range (600 cm vs 400–500 cm) and finer resolution (1 mm vs 1 cm).\n    \u003c\/div\u003e\n    \u003cdiv class=\"faq\"\u003e\n      \u003cstrong\u003eCan the entire module be submerged in water?\u003c\/strong\u003e\n      Only the transducer probe is waterproof and can be exposed to water.

The JSN-SR04T 2.0 operates down to 3.0V, so it is natively compatible with 3.3V boards like ESP32 and Raspberry Pi — no voltage divider needed on the ECHO pin.\n    \u003c\/div\u003e\n    \u003cdiv class=\"faq\"\u003e\n      \u003cstrong\u003eWhat is the minimum detectable distance?\u003c\/strong\u003e\n      The minimum range is 20 cm. Objects closer than 20 cm may not be detected reliably, which is a design tradeoff of the sealed transducer format.\n    \u003c\/div\u003e\n    \u003cdiv class=\"faq\"\u003e\n      \u003cstrong\u003eCan I use this for a water tank level monitor?\u003c\/strong\u003e\n      Yes.
