Features:

The MAX301 05 is an integrated particle detection module. Integrated internal LED, photodetector, optical element, and high SNR, low noise electronic circuit with ambient light suppression, and reliable motion artefact suppression. Simplifies the design process for fire alarm light smoke detection applications. Thanks to its extremely small size, it can also be used as a smoke detection sensor for mobile and wearable devices.

Product details

• Operating voltage: DC 5V
• Operating temperature: -40°C to +85°C
• Communication interface: IIC
• Module size: 24.6*14.5mm, with two M3 mounting holes

Pin definition

• VCC: Power positive
• GND: Ground
• SCL: I2C serial clock line
• SDA: I2C serial data line
• INT: active low interrupt, pulled-up resistor

Instructions for use

The module has internal pull-up resistors for the I2C data and clock lines, so the user does not need to pull up the resistors repeatedly.
