With the rapid growth in the number of private swimming pools globally, the functionality of old-fashioned pool robots can no longer meet the multifaceted needs of people for convenient, clean, and intelligent pool cleaning. The development of new types of pool robots has become a pressing need. Therefore, AUDIOWELL has launched the first underwater ultrasonic sensor, empowering the advancement of pool cleaning robots towards greater convenience, cleanliness, intelligence, and more, with mature and excellent sonar technology, thereby contributing to the industry's development.
Underwater Sonar Technology: Precisely Sensing Pool Environments
Underwater sonar technology
Underwater sonar technology utilizes the characteristics of sound waves propagation and reflection in water, employing positive and reverse piezoelectric effects and information processing for navigation and ranging. Users can detect underwater targets (including their presence, location, nature, direction of movement, etc.) and communicate through this technology, making it the most effective means of measurement and observation underwater currently available. Additionally, this technology can be used for depth detection in automotive water crossings.
Underwater Ultrasonic Sensor
The underwater ultrasonic sensor emits ultrasonic waves based on the principles of underwater sonar technology. It emits ultrasonic waves due to the reverse piezoelectric effect, which, upon encountering obstacles in the water, reflect back as echoes. These echoes are received by the sensor, and its built-in circuitry digitally converts the received signals. Additionally, using the MCU, it calculates the distance to the obstacle based on the Time of Flight (TOF) principle.
Long Detection Range, Assisting in Map Planning
The underwater ultrasonic sensor can detect environmental conditions within an 8-meter range, sensing the pool walls through echoes to navigate the pool cleaning robot. Based on this sensory data, the robot calculates its relative position and orientation in the pool, determines its location, and plans a cleaning path.
Small Measurement Blind Spot, Effectively Preventing Rough Collisions
AUDIOWELL's underwater ultrasonic Sensor has a measurement blind spot as small as 6cm, accurately detecting nearby objects, pool walls, steps, and obstacles. Sensors with digital communication capabilities can assist devices in decelerating in advance more quickly. Furthermore, sensors with small blind spots can provide the basis for the device to establish edge cleaning functions, ensuring thorough and efficient cleaning without omissions.
Low Power Consumption, Better Suited for Wireless Design
Wireless pool cleaning robots have become an industry trend. Creating wireless pool cleaning robots with strong battery life will be key to winning market competition. The underwater ultrasonic Sensor has low power consumption, does not affect the power needs of other components, and provides excellent conditions for enhancing the battery life of wireless pool cleaning robots.
IP68 Waterproof Rating, Suitable for Outdoor and Indoor Pools
The product has a waterproof rating of up to IP68, allowing it to work continuously underwater at a depth of 3 meters for 168 hours without failure. It has a wide operating temperature range, from 0.1 (non-freezing state) to 45°C, making it suitable for use in different environments such as outdoor and indoor pools.
There are currently over 26 million private swimming pools worldwide, increasing at a rate of 500,000 to 700,000 per year, making pool cleaning an economic development new blue ocean waiting to be explored. However, the premise for replacing the hard labor of pool cleaning with fully automated cleaning robots is cost-effectiveness. How to take the lead in this field still depends on the "intelligence" of the robots.
