STA-LR-A20m TOF Laser Ranging Radar Sensor is a cost-effective short-range laser ranging radar sensor that has been significantly upgraded and optimized based on DeTof. Its range can reach up to 20m, with a more efficient optical system and optimized circuit design. While ensuring higher ranging performance, it also exhibits excellent performance in blind spots and power consumption. With the upgrade and optimization of algorithms, the error performance in different environments has also significantly improved.
The STA-LR-A20 high-precision laser ranging radar lens adopts a coated glass lens to improve transmittance, achieve clearer ranging, and have higher glass hardness, scratch resistance, corrosion resistance, and extended service life. Built in temperature compensation enables precise measurement at a wide operating temperature range of -40 ° C to+70 ° C.It can be widely applied in fields such as unmanned aerial vehicle height control, intelligent transportation, intelligent parking lots, and smart agriculture.
