In AWE, ultrasonic sensor technology leader AUDIOWELL brought a new product for sweeping robot application - Ultrasonic Level sensors for water tank, which was praised by on-site audience after trying the demo device.
Ultrasonic Level sensors for water tank
Ultrasonic Level sensors for water tank monitors the height of the tank level in real time by transmitting ultrasonic waves and receiving the time difference between the reflected echoes. This non-contact liquid level sensor integrated transmitter drive, receive and collect, signal processing, parameter storage and communication interaction in one, the product as the core sensing components of the liquid level detection system, assembled in the sweeping robot's base station tank application, and water loops to form a warning system for the robot "no water warning", The product is used as the core sensing component of the liquid level detection system, which is assembled in the water ta
nk of the base station of the sweeping robot, and forms a warning system with the water filling loop to provide timely liquid level sensing for the robot's "no-water warning", "sewage tank full" and "insufficient water", and help it full-automatic cleaning.
Non-contact measurement for all types of liquids
Ultrasonic Level sensors for water tank can detect the liquid level of all kinds of liquids within the range of 15~500mm through echo detection technology and TOF measurement technology. Thanks to the non-contact detection method, the product can detect the liquid level without corrosion and other aggression, and is not affected by the chemical properties of the liquid, with excellent accuracy, flexibility, stability and reliability, can be pure water, sewage, foam water and other types of liquids to achieve accurate liquid level monitoring.
Intelligent sensing, precise warning
Ultrasonic Level sensors for water tank comes with signal output function, combined with AI algorithm, it can synchronously realize the warning of "no water warning", "sewage full tank", "insufficient water" and so on. As shown in the figure below, after the base station of the sweeping robot is powered on, the controller and MCU are started at the same time, and the MCU sends out pulse signals to drive the sensor to work, and the time difference between the sensor's emitted and received ultrasonic signals will be amplified and processed as an electrical signal, and then transmitted back to MCU, and then converted into a digital signal, which will be used to align with the set standard echo time difference, and to monitor the current liquid level whether it is in line with the cleaning requirements. By judging whether the liquid level reported by the sensor is lower (or higher) than the minimum (or maximum) level of the cleaning requirements, the controller will make a decision on the tank status such as "no water warning", "sewage full tank", "insufficient water" and so on. "no water warning", "sewage full tank", "insufficient clean water" and other water tank status to make early warning.
Continuous measurement, 24-hour monitoring
The continuous measurement advantage of AUDIOWELL's ultrasonic Level sensors for water tank can help the liquid level detection system of sweeping robots to achieve 24-hour all-weather monitoring function. When the product detects the liquid level, the sound wave emitted by the product can penetrate into the liquid through metal, plastic and other materials and accurately receive the echo signal, ensuring the realization of high-precision liquid level detection.
Good sealing performance, seamless load bearing
The water tank level sensor launched by AUDIOWELL is mainly composed of two parts: the silicone sleeve and the sensor, of which the sensor is fully encapsulated, with good sealing performance and protection level up to IP67, which is strong in waterproof and dust-proof ability. Assembled in the base station of the sweeping robot, the water tank level sensor is pressed under the water tank, and the silicone sleeve serves as the coupling layer between the sensor and the water tank, and the holes on both sides of the sensor can discharge the gap gas generated when the sensor is squeezed, ensuring seamless sensor bearing and guaranteeing high-precision detection results.
