Recently, Xiaomi officially released another smart home appliance under its brand Mijia - the Mijia floor sweeping robot. It is also said to be a highly intelligent robot that sweeps cleanly and quickly. Why is it a highly intelligent robot?
Because the robot is equipped with 12 different types of sensors: LDS laser distance sensors, ultrasonic sensors, collision sensors, etc., the sensors have their own roles, real-time monitoring, real-time mapping, intelligent planning paths, to avoid relying on a headless fly to bump around and sweep. What are the duties of these 12 types of sensors? Among them, the LDS laser ranging sensor is responsible for accurately detecting the indoor space; the cliff sensor is responsible for sensing the height of the steps to avoid falling and so on, and the ultrasonic sensor provided by Audiowell for the Mi Home Sweeper is mainly applied to sensing and measuring the distance of obstacles.
Ultrasonic sensors are responsible for sensing obstacles and measuring the distance to obstacles to avoid obstacles. Ultrasonic sensor is like a bat ultrasonic, the whole sensor by responsible for transmitting ultrasound and responsible for receiving ultrasound two parts, according to the time difference between transmitting and receiving can be calculated and get the distance between me and the obstacle, so as to avoid the collision, the transparent object can also be correctly sensed in advance of the deceleration.
At present, the ultrasonic sensors developed and produced by Guangdong Audiowell Sensing Technology Co., Ltd. are in the leading position in the market, and have been widely used in intelligent robot obstacle avoidance, UAV obstacle avoidance, automotive electronic distance measurement and other systems. Audiowell has also launched an application program - ultrasonic distance measurement module according to the market demand.
Ultrasonic Distance Measuring Module
The ultrasonic distance measurement module developed and produced by Audiowell utilizes non-contact ultrasonic distance measurement technology to achieve distance measurement, and converts the distance value into a responsive pulse output. The module adopts ultrasonic intelligent software processing technology, which improves the reliability of the distance measurement as well as the circuit's ability of anti-interference.
Audiowell ultrasonic distance measuring module features:
- Large measuring range, digital signal output
- Strong anti-interference ability, small blind spot
- Good directionality, fast response speed
