The HPS-16x series is a new generation of high-performance time-of-flight (ToF) infrared ranging sensor, equipped with optimized design of transmitting and receiving optical lens, suitable for high-precision, long-distance ranging occasions. Different from traditional technology, its measurement accuracy is not affected by the color and reflectivity of the measurement target. When the target is white, the measurement distance can reach up to 40 meters. The product is equipped with a high-power 850nm infrared VCSEL transmitter or infrared LED transmitter, combined with a high-sensitivity photodiode receiver and an internal integrated physical infrared filter, so that it can measure longer distances and has a stronger ability to resist ambient light interference; built-in Advanced embedded data processing and filtering algorithms achieve very stable and real-time measurement result output, which can be applied to drones for fixed-height flight, drone-assisted landing, distance detection, height difference detection, security and surveillance, parking lots Vacancy detection, industrial positioning and proximity sensors, etc.
