At present, optical sensors such as laser sensors have many applications, especially in many industrial fields and distance measurement research.When in confined space, the best solution is non-contact sensor system, etc.Laser sensors are very suitable for quality control and process monitoring research projects, as well as for automation, chemical industry, medical technology and special machine manufacturing.
Application fields of LUFTMY PM2.5 dust concentration laser sensor: air purifier, air conditioner, PM2.5 detector, range hood, smoke alarm, fresh air system, dedicated PM2.5 sensor, air detector, wearables, etc.
PM2.5 dust laser sensor module adopts Mie's spherical particle scattering principle, that is, laser sensor uses laser to irradiate suspended particulate matter in the air to produce light scattering, photoelectric detector collects scattering light intensity in a certain angle range, and converts the scattering light intensity into voltage linearly, and then sends it to data processing system. The data processing system carries out data processing according to the pre-programmed program, and obtains the equivalent particle size and the number of particles with different particle sizes per unit volume.
Laser sensors and other non-contact sensors are very suitable for measuring some complex structures.For example, in the automotive industry, some assembly products have some complex geometric shapes, and it is difficult to detect them with some contact sensors in normal time.Laser displacement sensor can solve this problem very well. Laser displacement sensor controls whether the size of headlamp module conforms to tolerance, so that it can work in assembly products.
Laser sensors are mounted on the chassis of automobiles. Sensors with high measuring frequency ensure that the number of measured values is analyzed.Laser displacement sensor measures the distance between the chassis and the ground, and the optical measurement principle of the sensor can analyze the inclination of the car.
Liquid level measurement is called harsh measurement application. In the whole sensor industry and research, liquid level measurement and distance measurement are very important, and also indispensable in the food industry, plastic industry and chemical industry.The measured material can exist in three material states: solid, liquid or gaseous. When the material is in liquid or solid state, the level can be measured by laser sensor. Liquid materials should be stationary and opaque. It should be noted that some solid materials have reflective properties that interfere with optoelectronic components or deflect laser beams.
Laser sensors and other optical sensors are more and more used in warehouse automation logistics. Goods are automatically controlled from warehouse to warehouse and delivered from warehouse. Accurate positioning of cargo, in a longer distance, laser sensors monitor clearance to locate the expected space of cargo, etc.
