Overview

The VL53L4EDV9DH/1 is a high-performance Time-of-Flight (ToF) ranging sensor from STMicroelectronics designed to operate in extreme environments with a temperature range of -40 to 105 degrees Celsius. It provides accurate distance measurements up to 130 cm regardless of target color or reflectance using an integrated VCSEL and SPAD array. This sensor communicates via a standard I2C interface and is housed in a compact 12-pin optical LGA package.

Why Choose This Part

The extended operating temperature range of -40 to 105 degrees Celsius makes this part suitable for automotive and industrial deployments that exceed standard consumer ratings. It features very low power consumption with a 6uA standby current and provides reliable distance data that is immune to ambient lighting conditions due to its 940nm VCSEL technology.

Applications

Industrial Robotics
Used for collision avoidance and short-range navigation in harsh factory environments where high temperatures are common.
Smart Building Systems
Enables presence detection and occupancy monitoring for lighting control and automated door systems.
Liquid Level Sensing
Measures the distance to a liquid surface in industrial tanks or containers using non-contact optical ranging.
Biometric Safety
Ensures correct user positioning for biometric scanners or security access panels.

Key Specifications

Output Type I2C
Sensing Distance 0 ~ 51.18" (0 ~ 130cm)
Voltage - Supply 2.7V ~ 3.4V
Operating Temperature -40degC ~ 105degC

Getting Started

To begin development, use the STSW-IMG034 X-CUBE-TOF1 expansion pack for the STM32Cube environment. Engineers can prototype quickly with the X-NUCLEO-53L4A3 expansion board which integrates seamlessly with the STM32 Nucleo ecosystem. Ensure the I2C bus is pulled up to the supply voltage, which should be maintained between 2.7V and 3.4V.
