MAX30102 Heart Rate Sensor Module

Discover the MAX30102 Heart Rate and Pulse Oximeter Sensor Module, a top - notch all - in - one solution for accurate heart rate and blood oxygen saturation monitoring. It comes with cutting - edge internal LEDs, photodetectors, optical elements, and low - noise electronics. These components work together to fight off ambient light interference, delivering precise readings in all sorts of conditions. Designed for modern innovators, this module is a breeze to integrate into mobile and wearable tech. It offers a comprehensive system solution that simplifies the design process. It runs smoothly with a single 1.8V power supply for the module and an extra 3.3V for the internal LEDs. Data transfer is seamless via a standard I2C - compatible interface, making it easy to communicate with most microcontrollers. One of its best features is the software - enabled shutdown mode. It cuts the standby current to zero without shutting down the whole system. This is super useful in power - hungry devices like wearables, fitness trackers, smartphones, and tablets.

Package Contents: - 1 x MAX30102 Heart Rate and Pulse Oximeter Sensor Module, ready for immediate project integration. The MAX30102 is perfect for developers aiming to add health monitoring to their wearable or portable projects. It offers unmatched accuracy, efficiency, and flexibility for cutting - edge applications.

Using the MAX30102 Heart Rate and Pulse Oximeter Sensor Module is easy. First, connect it to your device following the pin configuration details. The VIN can take an adjustable voltage from 1.8V to 5V DC, so make sure you set it according to your device's power needs. Use the SCL and SDA pins for I2C bus connections for clock and data transfer. The INT pin can be used to get real - time alerts. When using it, keep in mind that it works best in different temperature conditions, from - 40°C to 85°C. But try to avoid exposing it to extreme humidity or direct sunlight for long periods as this might affect its performance. For maintenance, keep the module clean. You can use a soft, dry cloth to wipe it if it gets dirty. Also, since it has a low current consumption of max 6mA, it's energy - efficient, but don't leave it connected to power when not in use to save even more energy. The software - enabled shutdown mode is handy for this. Just activate it, and the standby current will go to zero without shutting down the whole system. Enjoy accurate health monitoring with this great module!
