This the MAX30105 an integrated particle sensor. This device includes internal LEDs, Photodetectors, Optical Elements, with advance low noise electronics and light blocking. This provides a complete system on chip solution to ease the design process of a smoke detection applications including fire alarms, due to its extremely small size package, and can be also used as a smoke detection sensor for wearable and mobile device, home electronics, medical equipment’s / appliance, home and business network communication appliances, home and office printing devices etc. this device also suitable for fire alarm system, building automations, and industrial equipment’s etc.
The MAX30105 runs on ultra-low power operation at single 1.8v power supply and a separate 5v power supply for the internal LED’s can adopt -40 degree Celsius to +85 degree Celsius it communicates through a standard i2c compatible protocol interface, and can be switch off though software with zero standby current, allowing the power rails to remain powered every time.
