4 in 1 sensor

ygC4dpFFUUjGfgfz-16.pngThe iTriangle 4 in 1 sensor is based on the IMU 10DOF v2.0 and is an upgraded version of the IMU-10DOF and replaces BMP180 with BMP280. As the successor to the widely adopted BMP180, the BMP280 delivers high performance in all applications that require precise pressure measurement. This module is based on the MPU-9250 and BMP280. The MPU-9250 is a 9-axis MotionTracking device that combines a 3-axis gyroscope, 3-axis accelerometer, 3-axis magnetometer and a Digital Motion Processor (DMP). The BMP280 is a high precision, ultra-low power digital pressure sensor for consumer applications. This module is very suitable for application in smartphones, tablets and wearable devices.

Specifications


  • I2C Grove interface, including GND, VCC, SDA and SCL
  • MPU-9250 I2C address selectable
  • Low Power Consumption
  • 400 kHz Fast Mode I2C for communicating with all registers

Hardware Overview


  • MPU-9250 I2C address select pad. Default connection a and b, address is 0x68. If b and c connection, address is 0x69
  • MPU-9250 interrupt pin. The interrupt should be configured, available interrupt sources are: motion detection, fifo overflow, data ready, i2c master error
  • Orientation of Axes. The diagram below shows the orientation of the axes of sensitivity and the polarity of rotation.
  • The BMP280 is an absolute barometric pressure sensor especially designed for mobile applications. The sensor module is housed in an extremely compact 8-pin metal-lid LGA package with a footprint of only 2.0 × 2.5 mm and 0.95 mm package height. Its small dimensions and a low power consumption of 2.7 μA @1Hz allow application in battery driven devices such as mobile phones, GPS modules or watches.
