The MAX30105 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 senor for mobile and wearable devices.
The MAX30105 operates on a single 1.8V power supply
and a separate 5.0V power supply for the internal LEDs.
It communicates through a standard I 2 C-compatible inter-
face. The module can be shut down through software with
zero standby current, allowing the power rails to remain
powered at all times.
