ST offers infrared time-of-flight sensor
The company claims the VL53L0 is the smallest time-of-flight (ToF) module in the world and the first to use a 940nm infrared light source. One results is that the VL53L0 can range faster, over longer distances, and more accurately than previous members of ST’s FlightSense family. The unit integrates a 940nm wavelength VCSEL light source and a single photon avalanche diode (SPAD) detector as well as microcontroller to implement digital detection algorithms. The unit measures 4.4mm by 2.4mm by 1mm.
It can perform a measurement operation in typically less than 30ms at distances of greater than 2m.
The VL53L0 module includes an I2C interface and comes with API drivers. It is in production and priced from $1.75 at the minimum order quantity of 5,000 units.
