Description

The BH1715FVC-TR is a high-precision digital ambient light sensor from ROHM Semiconductor Semiconductor. It converts light intensity into a digital signal via its integrated ADC, communicating directly with a host microcontroller via the I2C bus, eliminating the need for external signal conditioning. Its built-in infrared filtering ensures accurate measurement of visible light, minimizing the impact of IR sources.

Engineered for reliability in harsh environments, the sensor operates across an extended industrial temperature range. This makes it suitable for applications from consumer electronics to automotive and industrial control systems where consistent performance under varying thermal conditions is critical.

Key Features

  • Digital output with I2C bus interface (FM mode)
  • Wide detection range (typical 0 - 65535 lx)
  • Excellent spectral response matching the human eye (CIE 1931)
  • Integrated IR-cut filter for improved accuracy
  • Low power consumption for energy-sensitive designs
  • Robust WSOF-6 package for surface-mount assembly
  • RoHS compliant for global environmental standards

Applications

  • Automatic display brightness adjustment in smartphones, tablets, and laptops
  • Backlight dimming control for automotive instrument clusters and infotainment systems
  • Energy-saving lighting control in smart home and building automation systems
  • Ambient light monitoring in industrial HMIs and outdoor digital signage

Frequently Asked Questions

What is the communication interface for the BH1715FVC-TR sensor?

The BH1715FVC-TR uses a standard I2C (Inter-Integrated Circuit) serial communication interface. This allows for easy connection to microcontrollers like Arduino, Raspberry Pi, or ESP32 using just two wires (SCL and SDA), simplifying circuit design and firmware development.

What is the typical operating voltage range for this sensor?

The sensor is designed to operate from a supply voltage (VDD) typically between 2.4V and 3.6V. It is compatible with common 3.3V logic systems. Always consult the official ROHM Semiconductor datasheet for absolute maximum ratings and detailed electrical characteristics before final design.

How does the spectral response of this sensor compare to other light sensors?

The BH1715FVC-TR incorporates an optical filter to tailor its spectral sensitivity to closely match the CIE 1931 standard photopic luminosity function, which approximates human eye response. This results in more accurate perceived brightness measurements compared to sensors without such filtering, especially under artificial light sources.
