A high-precision ambient light sensor housed in a transparent semisphere case for optimal light-gathering performance. With a wide 0–200 klx detection range and I2C communication, this sensor is ideal for applications requiring accurate ambient light measurement across a broad range of conditions.

The on-chip photodiode features a spectral response optimised to mimic the human eye's perception of ambient light, with built-in IR and UV blocking. An adaptive gain block automatically selects the optimal lux range to maximise accuracy at any light level.

Key Features

  • Wide Detection Range – 0 to 200 klx covers everything from moonlit nights to direct sunlight
  • Human Eye Response – Spectral response matched to human visual perception
  • IR & UV Blocking – Filters out infrared and ultraviolet for accurate visible light measurement
  • Adaptive Gain – Automatically optimises counts/lux for the current light level
  • I2C Interface – Simple digital communication with microcontrollers
  • Transparent Semisphere Housing – Enhanced light collection from all angles
