█Performance parameters

█ SDA---22m Infrared SPAD Laser Ranging Module TOF Pulse Laser Ranging Module

Fully integrated single-channel dToF in small size

High-sensitivity infrared-enhanced SPAD sensor

High resistance to ambient light, reflectance correction function

I2C/SPI/UART is supported

22 meters, available indoors and outdoors

High precision: pulsed, centimeter-level accuracy

SDAM is a fully integrated single-channel dToF ranging small module, integrating a self-developed high-sensitivity infrared-enhanced SPAD sensor with a range of 20m. The on-chip integration of time-dependent photon threshold algorithm, histogram statistical algorithm, and fast TDC architecture achieves high-precision ranging, 12m@100KLux anti-ambient light capability, and reflectance correction function. The SDAM integrated power module operates from a single 3.3V supply with built-in temperature compensation. Supporting I2C, UART interfaces, easy integration and use, and a compact and reliable optical LGA package with a small size and light weight, it is an excellent choice for micro-small dToF applications.

█ Reason for model selection

This long-distance laser ranging module not only has an ultra-small size (21*15*7.87mm), but also is lightweight, easy to integrate and use. Customers are often used in the construction industry, coal mining industry, sweeping robot industry, measuring container deformation, interior decoration room height and width measurement, etc.
