The VL53L4ED is a time-of-flight (ToF) ranging sensor for use in proximity-sensing applications that require high accuracy over a short distance up to 1.3 m in normal temperatures, and up to 1.15 m at high temperatures up to 105°C.
Special settings also provide for accurate distance measurement at a range of up to 800 mm when operating in dim light of up to 5 klux in intensity.
The VL53L4ED embedded on-chip processing helps to reduce design complexity and bill-of-materials cost relieving the burden on the host, so a less powerful and less expensive microcontroller can be used.
Like all ToF sensors based on ST FlightSense™ technology, the VL53L4ED performs absolute distance measurement regardless of the target color and reflectance.
The VL53L4ED combines an infrared vertical-cavity surface-emitting laser (VCSEL) emitter and a single-photon avalanche diode (SPAD) array of photodetectors. Diffractive optical elements above the emitter enable the sensor to perform ranging in various ambient lighting conditions, and through a range of cover glass materials.
The VL53L4ED is a direct derivative of the VL53L4CD, with which it is pin-compatible.
Part Number: X-NUCLEO-53L4A3
The X-NUCLEO-53L4A3 from STMicroelectronics is an expansion board for any STM32 Nucleo board equipped with Arduino R3 connectors which enables designers to develop applications using the VL53L4ED short-range time-of-flight (ToF) proximity sensor.
The expansion board is supplied with a cover glass holder in which designers can fit a spacer of 0.25 mm, 0.5 mm, and 1 mm height below the cover glass to simulate a variety of air gaps. A small oval cover glass fitting the sensor is included.
