Buried water detector, also known as buried water monitor, buried liquid level meter and buried water detector, can monitor the water level in low-lying sections of urban areas in real time and realize automatic alarm, and can be installed in multiple urban scenes.

Working principle: According to the liquid-type ultrasonic sensor, the distance of sound wave transmission is obtained by measuring the time interval from the emission to the reception of sound waves, combined with the sound speed of the compensated sound wave.

The time difference between the ultrasonic wave emitted from the installed sensor and the received echo on the water surface can be used to determine the current liquid level height.

Power supply mode: Built-in battery power supply (3.6V lithium-sulfur battery 38000mAH)

Battery life: More than 5 years of continuous operation without water accumulation (without water accumulation, one upload every 5 minutes; with water accumulation, one upload every 1 minute).

Water level range: ≤1.5m

Water level error: 1cm

Resolution: 1mm

Output signal: LORA wireless spread spectrum signal

Case material: 304 stainless steel

Protection level: IP68

Installation method: The installation method is adopted by burying it on the ground, and a mounting hole is opened at the equipment installation position on the road surface.

After the hole is completed, place the equipment vertically into the installation hole, pour the filler to fix the equipment.

Note: Ensure the top remains level to avoid affecting the measurement.

Equipment dimensions: height 187 mm, cavity diameter 60 mm, top disk diameter 120 mm.

Communication interface: A low-power wireless standard developed by Semtech Company, LORA wireless communication, is adopted. This communication method achieves the unification of low power consumption and long distance.

Wireless long-distance communication with the unique LORA wireless communication protocol of our company and the host of our company's waterlogging monitoring station, with a communication line of sight of up to 800m.

Configuration method: The mobile APP configures the device through Bluetooth wireless link.
