Smoke Click Board™

Product Code: MIKROE-2560

The Smoke Click Board™ carries the MAX30105 high-sensitivity optical sensor for smoke detection. The click is designed to run on either 3.3V or 5V power supply. It communicates with the target MCU over I2C interface with additional functionality provided by the INT pin on the mikroBUS™ line. MAX30105 SENSOR FEATURES The MAX30105 is an integrated particle-sensing module. It includes internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection. The sensor can detect a wide variety of smoke particle sizes. The MAX30105 also has an on-chip temperature sensor for calibrating the temperature dependence of the particle sensing subsystem. The temperature sensor has an inherent resolution 0.0625°C. POWER CONSUMPTION Power supply current in Shutdown mode is typically 0.7μA. The module can be shut down through software with zero standby current, allowing the power rails to remain powered at all times. BUILDING AN IOT SMOKE DETECTION DEVICE Adding WiFi connectivity to your smoke detection sensor is always a good idea.

You can get a message as soon as the level of smoke goes over the set threshold. For example, Smoke click and WiFi ESP click together would do that job wonderfully.
