L07 Datasheet

DYP Sensor L07 IP67 Waterproof Liquid-Tank Level Ultrasonic Sensor 1.5-300 cm For Top-Mounted Liquid-Level Detection

The DYP Sensor L07 IP67 waterproof liquid-tank level ultrasonic sensor is designed for accurate non-contact liquid-level detection in compact tanks, reservoirs, plant boxes, air-disinfector boxes, and soilless-cultivation systems. With a 1.5 cm to 300 cm measurement range and millimetre-level resolution, it is well-suited for applications where a short blind-zone, stable readings, and flexible installation are required.

The L07-module is developed to address common issues in ultrasonic liquid-level sensing, such as large blind-areas, wide measurement angles, long response times, and limited installation adaptability. Its top-mounted design supports reliable liquid-level monitoring while reducing contact with liquids, making it useful for nutrient-solution monitoring, disinfectant-level monitoring, and water-tank level detection.

This ultrasonic liquid-level sensor supports multiple output options, including UART automatic-output, UART control-output, RS485, IIC, and PWM pulse-width output. It also supports adjustable signal levels, 6 algorithm modes, 5-level noise-reduction settings, and a fast response time of up to 13 ms. The IP67 waterproof structure, wide 3.3 V to 12 V supply range, and -25°C to +65°C operating temperature make it suitable for demanding indoor and outdoor liquid-level applications.
