Model PMA2131 Digital Scotopic Light Sensor

Solar Light’s Model PMA2131 Digital Scotopic Light Sensor is a portable Lux detector with spectral response following the CIE Scotopic Luminous Efficiency Function (which mimics the human eye’s response in low light conditions.) The angular response of the PMA2131 sensor is cosine corrected, and suitable for measurements of diffuse radiation or radiation from extended sources. Several packages are available for different types of environments, including standard, low profile, weatherproof, and waterproof.
