Product Details

Maxima Optical Mouse Sensor

The Maxim optical sensor is an integrated particle sensing module. It includes internal LEDs, photodetectors, optical elements and low noise electronics with ambient light rejection. The MAX30105 provides a complete system solution to ease the design-in process of smoke detection applications including fire alarms. Due to its extremely small size, the MAX30105 can also be used as a smoke detection sensor for mobile and wearable devices. The sensor operates on a single 1.8V power supply and has separate 5V power supply for the internal LEDs. This module communicates through a standard I2C-compatible interface.
