Ambient Light Sensor(0-200klx)
We have ✅ 2 available of the DF-SEN0390 in our Sydney warehouse. An extra 311 units available with a short lead time.
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.
