1.The MAX30105 is an integrated particle-sensing module.

2.It includes internal LEDS, photo detectors, optical elements.

and low-noise electronics with ambient light rejection.

3.The MAX30105 provides a complete system solution to ease the design-in process of smoke detection applications including fire alarms.

4.Due to its extremely small size, the MAX30105 can also be used as a smoke detection sensor for mobile and wearable devices.

5.The MAX30105 operates on a single 1.8V power supply and a separate 5.0V power supply for the internal LEDS.

6.It communicates through a standard I2C-compatible interface.

7.The module can be shut down through software with zero standby current, allowing the power rails to remain powered at all times.
