Description

The VCNL4200 integrates a long-distance infrared proximity sensor and a high-resolution ambient light sensor into a single, compact surface-mount package. Utilizing a 940 nm IRED and advanced CMOS process, it provides precise digital measurements for both proximity (up to 1.5 meters) and ambient light intensity (0.003 to 1573 lux). Its parallel operation structure allows simultaneous PS and ALS readings without interference.

Designed for reliability, the module incorporates Filtronâ„¢ technology to effectively cancel out background light noise, ensuring stable performance even behind dark or high-transparency lenses. The digital I2C output simplifies connection to 3.3V or 5V logic systems, making it suitable for a wide range of automated and energy-saving applications.

Key Features

  • Combined proximity (PS) and ambient light sensing (ALS) in one IC
  • Long-distance proximity detection range from 0 to 1500 mm
  • High 16-bit resolution for precise ambient light measurement
  • Integrated 940 nm infrared emitter (IRED) with programmable pulse current up to 800 mA
  • I2C digital interface with 1.8V to 3.6V bus voltage support
  • Filtronâ„¢ technology for superior background light suppression
  • Supports operation behind dark or tinted optical lenses
  • Low operating voltage range from 2.5V to 3.6V DC

Applications

  • Presence detection for automatic display wake-up in printers, copiers, and smart appliances
  • Collision avoidance and object detection in robotics, drones, and automated guided vehicles (AGVs)
  • Proximity-based lighting control and energy management in office buildings, corridors, and smart homes

Frequently Asked Questions

What is the maximum sensing range of the VCNL4200 proximity sensor?

The VCNL4200 proximity sensor has a maximum detection range of up to 1500 mm (1.5 meters). Its high sensitivity and integrated 940 nm IRED with programmable pulse current enable reliable long-distance object detection, suitable for applications like collision avoidance and presence sensing.

What is the operating voltage and I2C logic level for this module?

The sensor's core operating voltage range is 2.5V to 3.6V DC. The I2C communication interface supports a separate logic voltage range from 1.8V to 3.6V, making it compatible with both 3.3V and lower-voltage microcontrollers without requiring level shifters.

Can this sensor operate behind a dark or tinted lens?

Yes, the VCNL4200 is specifically designed to support low transmittance (dark) lens designs. Its Filtronâ„¢ technology and high-sensitivity photodiodes effectively cancel background light, allowing it to function accurately even when mounted behind tinted covers or dark glass.

How do I read data from the VCNL4200 sensor?

Data is read via the standard I2C serial interface. The proximity and ambient light values are provided as digital codes (12-bit for proximity, 16-bit for ALS). You can use common microcontroller libraries to communicate with its I2C address and read the respective data registers.
