Not recommended for future designs. Please refer to MAX30101.
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.

Evaluation Kit for the MAX30105
Product Detail
The MAX30105 evaluation kit (EV kit) provides a proven design to evaluate the MAX30105 particle-sensing module. The EV kit consist of two boards. USBOSMB is the mother board and MAX30105DBEVKIT is the daughter board that includes the MAX30105 and an accelerometer. The EV kit is powered using the USB supply to generate +1.8V for the sensor and +4.5V for the internal LEDs of the MAX30105, and +3.3V for the accelerometer. However, users do not need the accelerometer to evaluate the MAX30105.
The EV kit comes with a MAX30105EFD+ installed in a 14-pin OESIP package.
Applications
- Fire Alarms
