Shown below is a LPPHOTO03BL illuminance (lux) sensor for outdoor use.

The sensor provides a raw millivolt (mV) output. For the unit shown in the photo, the sensitivity is 0.156 mV per klux. At the maximum range of 150 klx, the output reaches 23.4 mV. Because the signal level is relatively low, a high-resolution data logger capable of measuring millivolt signals is required to use this unit effectively.
