Project Description

Water Level Sensors

The Best IoT Sensing Solutions—Directly from the street


water level sensor

Water level sensor: To monitor the water level in different situations

Water Level Monitor/Flood Detector, using leading capacitive sensor to detect water surface position, built-in Bore OS IoT operating system and GSM/GPRS communication module. When the water reaches the specified position, the systemdetects a change in the sensor signal, after filtering and analysis, it will send the message to IoT server.

Water Level Monitor/Flood Detector applies to : tap water,domestic water, river water, waste water, weak acid and alkaline
water, water treatment chemicals, textile printing and dyeing water, industrial waste water, etc. Special models can also be used in ultra pure water, reverse osmosis water or distillation.

Key Features

• Stain resistance, anti-tilt, weak acid and alkali salt, able to work in the influence of magnetic field, metal body, water pressure change and raid of light, no dead zone
• Without any mechanical parts on the outside, Not afraid of the influence of floating objects
• With real-time clock function, it can perform periodic selftest reporting
• Support for setting reporting period
• Support to report the battery voltage
• Support the remote configuration

Project Goal Recognition

We understand each customer has their own unique knowledge about industrial smart electronics solution, they may face different challenges, thus have different project requirements with different expectation.

Due to the above, the starting point of our job is to recognize the actual project target, helping our customers address the multiple aspects of the whole project, from installation, user experience to maintenance.


Our product team together with skilled engineers, project managers and customer success executives would engage directly with customer’s cross-functional teams, to obtain the full view of client’s challenge as well as the possible untapped pain, while presenting clients the existing solutions & case studies , thus clients could make better decisions about what they should buy.

Research & Design

We are able to develop the customized hardware and software precisely as per clients confirmed requirements.


We would quickly develop a concept-of-approval prototype to realize what clients need, in order to validate the requirements

Test & Trial

We would implement comprehensive testing via trial production, ensuring zero risk of mass-production failure.

Mass Production & Launch

Mass productions come as carefully planned, informed of our customers, with daily logging data shared so that shipment schedule could be reassured.
