GY-271 Compass Module Features
Magnetic current and field have directly relation with each other. When current flows in a wire (electrons start travelling in one direction), a magnetic field is created. The main idea of compass sensors is based on this relationship. The direction of the earth's magnetic field affects the flow of electrons in the sensor. By measuring these changes in current, the sensor will be able to detect direction.The GY-271 module uses the QMC5883L chip to detect magnetic fields an...

MMA7361 Accelerometer Module Features
The MMA7361 is a 3-axis accelerometer with ± 1.5g to ± 6g measuring range. You do not need a library and complex code to use MMA7361 accelerometer. In this module, there is an analog output voltage for each axis acceleration. As a result, you can read and analyze sensor's outputs using an analog-to-digital converter.
You can download the datasheet of this module here.

MAX30102 Heart Rate Module Features
MAX30102 sensor is used to detect blood oxygen and heart rate. First, infrared radiation is sent and reflected by hitting the finger, and then the amount of oxygen in the blood is determined by measuring the wave amplitude. Heart rate is also obtained by analyzing the time series response of this radiation.The MAX30102 is an integrated module compatible with the Arduino and STM32. It integrates a red LED with an infrared LED, a photoelectric detector, an optical devi...
ADXL345 Accelerometer Module Features
ADXL345 accelerometer sensor can measure angle orientation and object path. The sensor can do that in three X, Y and Z axes. It can also measure dynamic and static acceleration forces. Dynamic acceleration force is due to motion and vibration and static acceleration is caused by gravity. The sensitivity range of the ADXL345 accelerometer sensor is from +-2g to +-16g. (g is approximately 9.8) For example, when this sensor is placed on a flat surface, its value is +1...
