MAX30105 光學感測器 顆粒感應 煙霧探測火焰傳感器模組

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.

The MAX30105 utilizes a red LED, a green LED, and an IR (Infrared) LED for presence sensing, heart-beat plotting and heart-rate monitoring among its multitude of uses, including Pulse Oximetry. The MAX30105 is designed to operate at 5V and can communicate with both 3.3V and 5V microcontrollers. We’ve also written an Arduino library for the MAX30105 Breakout which takes care of all of the I2C communication, bit shifting, register writing and sample reading.

• Built-in Red, IR, and Green LEDs
• 5V operation (3.3V is allowed, but green LED is not guaranteed to operate)
• Onboard 1.8V regulation and I2C interface circuitry
• Sensitivity configurable down to 7.81pA
• 3200Hz maximum sample rate
• Built-in 32 sample FIFO (First In, First Out)
• Applications include presence detection, distance sensing (18″ max), pulse oximetry, blood oxygen saturation level (SpO2), smoke and particle detection
