Key Features of Waterproof Ultrasonic Sensor
- Fully Waterproof Probe: IP67/IP68-rated transducer probe withstands rain, splashes, submersion, dust, and humidity - ideal for outdoor and underwater deployments.
- Separated Probe & Driver Board: The sealed ultrasonic transducer connects to a compact driver PCB via a long shielded cable, allowing flexible mounting in tight or exposed locations.
- Wide Detection Range: Measures distances from 25 cm up to 450 cm with +/-1 cm accuracy, suitable for liquid-level monitoring, obstacle detection, and proximity sensing.
- Simple TTL Interface: Standard trigger/echo pulse protocol - drop-in compatible with HC-SR04 code libraries on Arduino, ESP32, Raspberry Pi, and more.
- Low Power Consumption: Draws only ~8 mA at 5 V, making it well-suited for battery-powered and solar-powered remote installations.
- Wide Voltage Tolerance: Operates reliably from 3.0 V to 5.5 V, directly compatible with both 3.3 V and 5 V logic microcontrollers.
- Stable in Harsh Conditions: Performs across a -20 degreesC to +70 degreesC temperature range with consistent readings even in high-humidity or condensation-prone environments.
- Long Shielded Cable: ~2.5 m cable between probe and controller board reduces electrical noise and allows the electronics to be housed safely away from wet zones.
- Battle-tested in real-world outdoor and industrial projects by our engineering community
- Perfect upgrade over non-waterproof HC-SR04 sensors for any project exposed to moisture
Perfect For
- Water Tank / Reservoir Level Monitor: Mount the waterproof probe above a tank to continuously measure water level. Pair with an ESP32 and Blynk or ThingSpeak for real-time IoT alerts on your phone.
- Automated Garden Irrigation: Detect water level in a sump or rain barrel and trigger a pump relay when levels are sufficient - fully weatherproof for year-round outdoor use.
- Vehicle Parking / Reverse Assist: Install on a car bumper or garage wall to measure distance to obstacles. Drive a buzzer or LED bar for audible/visual proximity warnings.
- Flood & Drain Water Alert System: Place the sensor in drainage channels, basements, or low-lying areas. Send SMS or push notifications when water rises above a critical threshold.
- Robotics Obstacle Avoidance (Outdoor): Equip autonomous rovers, agricultural bots, or delivery robots with waterproof ultrasonic sensing for reliable navigation in rain or mud.
- Industrial Bin / Hopper Fill-Level Detection: Monitor grain, sand, or waste levels inside bins and hoppers in dusty, humid factory environments where standard sensors fail.
- Weather Station Integration: Combine with rain, temperature, and wind sensors for a complete outdoor weather station - the waterproof rating ensures long-term reliability.
- Learning & Education: Excellent hands-on
