Ultrasonic underwater ranging sensor
The L04 module is an ultrasonic underwater obstacle avoidance sensor designed based on underwater applications. Its features include small size, short blind area, high precision, and good waterproof performance. It can work stably at a water depth of 10 meters, with a range of 600cm and a centimeter-level blind area. Various output options: UART controlled, RS485 output.
•Working voltage: 5~24V
• Measuring range: 2cm～300cm and 5cm～600cm optional
• Blind zone minimum: 2cm
•Multiple output modes: UART controlled, RS485 Optional
•Protection grade IP68, can work under 10 meters water depth
• Average working current ≤ 20mA
• Ranging accuracy within 2 meters ±(0.5+S*0.5%) cm, S means measuring distance
• Working temperature: -15°C to 55°C
•Module address, angle, baud rate modification available
•Protection grade: IP68, can work under 10 meters water depth
• Small size, light weight module
• Designed for easy integration into your project or product
