High-quality materials ensure reliable performance. Typical applications include outdoor robot obstacle avoidance, liquid level measurement, water level measurement, trash can detection, and other distance measurement applications. The module is waterproof and dustproof, suitable for wet and harsh environments. Ultra-low standby power consumption makes it ideal for battery-powered applications. RCWL-1670 is a waterproof, transceiver-split ultrasonic ranging module with a measuring range of 2 cm to 400 cm. It operates on a wide voltage range of 3–5 V, with standby current of 1.5 µA at 3.3 V and 3.5 µA at 5 V. The module includes a waterproof ultrasonic transducer and receiver pair, along with a control circuit. External software is compatible with the HC-SR04 module. Operating voltage: 3–5 V Operating current: 6 mA Standby current: 1.5 µA at 3.3 V / 3.5 µA at 5 V Software compatibility: HC-SR04 Blind zone: 2 cm Maximum typical range: 4 m Measurement interval: 50 ms Color: As shown Material: PCB Package contents: 2 × Ultrasonic Range Finder Modules
