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 sensor 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 I2C-compatible interface. The module can be shut down through software with zero standby current, allowing the power rails to remain powered at all times.

Along with Maxim’s sensor, customers need smart algorithms to detect the particles of interest. Maxim is partnering with Valor Inc. to develop state-of-the-art algorithms for smoke detection applications using the MAX30105. Contact Valor for licensing information at
