The sweeping robot has been a hot seller in the smart home, which brings a lot of convenience to people's life. For many lazy people who do housework, it is simply a household cleaner.Now the intelligent sweeping robot has been able to sweep the floor, mop the floor, charge and other work independently. What technical support is needed for the realization of these functions?Here's a look at the technology in the sweeper and how the sweeper USES a dust sensor.

How does the intelligent sweeper use dust sensor

To put it simply, we can think of a sweeping robot as a mini vacuum cleaner with wheels, but wheels and the ability to vacuum are only the most basic elements of a sweeping robot.To become intelligent, it must be supported by sensors of all kinds.There are more than a dozen sensors on the body of a sweeping robot, just like our eyes and ears, so that the sweeping robot can avoid obstacles and avoid repeated cleaning.Without sensors, the robot can't even charge itself.

The robot is equipped with a variety of range finders and sensors, which are the basis for the robot to sense the external environment and make optimal decisions in a timely manner.Ultrasonic sensors can continuously emit ultrasonic signals outward, and receivers use the reflected signals to determine the size and distance of obstacles in front of them.Infrared ranging sensor is emitted infrared signal, the intensity of the reflected infrared signal can also be used to judge the distance of the obstacle.Contact sensors can be divided into inductance, capacitance, potentiometer and Hall displacement sensors, which can measure the size of space and the height of desks and chairs to prevent the floor robot from getting out after drilling into the bottom.The anti-collision sensor can be realized by photoelectric switch, which can react in time after the collision.Anti-drop sensor is generally placed under the floor robot, and ultrasonic ranging is mostly used to sense the ground height in front to prevent falling on the stairs.

However, sweeping robots are also necessary for dust sensors.Here, I would like to share with you a LUFTMY LD13 dust sensor, which USES MIE ball scattering principle to detect ultra-small particles of 0.1 m in particle size, obtain accurate particle concentration data and display real-time cleanliness data of the ground, so as to better complete the task of cleaning dust, hair fiber and other particles.
