The LTR-303ALS is an ultra-low cost($0.56 in 100piece quantity), ultra-small, I2C Ambient Light sensor. The LTR-303ALS comes in a 2.0×2.0x0.7mm 6pin DFN package. The LTR-303ALS has an operating voltage of 2.4-3.6V with I2C operation down to 1.7V. The LTR-303ALS provides a full dynamic range from 0.01-64K lux while providing close to the eye spectral response with immunity to IR/UV light sources and automatically rejects 50/60Hz light flicker. There are 6 gain settings available 1X, 2X, 3X, 4X, 8X, 48X, and 96X) to the user and provides a 16-bit effective resolution output.

The smSENSR-LTR-303 provides an easy to use, low-cost, ultra-small breakout board that can be soldered directly into a prototype or can be used with a standard breadboard. The smSENSR-LTR303 pins are all mapped to standard 2.54mm/0.1” headers. The header-header spacing is 7.62mm(300mil).

The smSENSR-LTR303 can be plugged into ANY of the 8pin smBLOCK I2C sockets in the smWSP and smWSP-ARD rapid prototyping sensor plugin boards. More info provided later in document.

All SMSTRS smMEM, smSENSR, smCOM, smBAT, smPWR products are compatible with the Sensor Maestros Wireless Sensor Platforms that provide Rapid prototyping for Sensor and BTLE applications.
