Ultra-Low Power Time-of-Flight sensors
To achieve the lowest power consumption possible using our Time-of-Flight (ToF) sensors, we have created a set of drivers that effectively configures a FlightSense™ sensor as an energy-saving proximity detector. Moreover, as soon as an object is detected, the driver switches the sensor back into standard ranging mode taking full advantage of our Time-of-Flight (ToF) technology.
Fully embedded in the firmware, the sensor's settings and ranging flows are especially designed to significantly reduce power consumption.
FlightSense™ single ranging sensors with Ultra-low-power (ULP) mode
VL53L1CX
VL53L3CX
VL53L4CD
Able to detect objects at up to 1400 mm with just 65 μA current consumption at 1 Hz ranging frequency in ULP mode
The ultra-low-power driver (STSW-IMG032) can easily set the VL53L1CX FlightSense™ sensor in ULP mode as an energy-saving proximity detector.
As soon as the sensor detects an object, the driver switches the sensor back into ranging mode with accurate ranging up 4 meters, fast ranging frequency (50 Hz) and customized field of view (FoV).
Able to detect objects at up to 840 mm with just 55 μA current consumption at 1 Hz ranging frequency in ULP mode
The ultra-low-power driver (STSW-IMG033) can easily set the VL53L3CX FlightSense™ sensor in ULP mode as an energy-saving proximity detector.
As soon as the sensor detects an object, the driver switches the sensor back into full histogram ranging mode with accurate multi-target ranging up 5 meters using ST histogram algorithms, cover glass crosstalk immunity beyond 80 cm, and dynamic smudge compensation.
Able to detect objects at up to 1100 mm with just 55 μA current consumption at 1 Hz ranging frequency in ULP mode
The ultra-low-power driver (STSW-IMG034) can easily set the VL53L4CD FlightSense™ sensor in ULP mode as an energy-saving proximity detector.
As soon as the sensor detects an object, the driver switches the sensor back into ranging mode with accurate ranging from only 1 mm up to 1300 mm. Its new-generation laser emitter with 18° FoV improves performance under ambient light, with a ranging speed up to 100 Hz.
