Smoke click

Smoke click is an integrated optical smoke detector, based on the MAX30105 chip. The MAX30105 is a highly sensitive smoke detector, and includes built-in LEDs, photo detectors, and low-noise electronics which automatically reject ambient light. It can detect a range of smoke particle sizes. A temperatur sensor for calibration is also built in, with a resolution of 0.0625°C.

* Runs on 3.3V or 5V supply voltage.
* Communicates over I2C.
