Compass Click is an add-on board in mikroBUS form factor. It features LSM303DLHC ultra compact high performance e-compass module. It includes specific sensing element and an IC interface capable of measuring both linear acceleration (full-scale of ±2g/±4g/±8g/±16g) and magnetic field (From ±1.3 to ±8.1 gauss full-scale) and provides a 16-bit data output through I2C interface. Readings received from the IC can be processed and used to determine earth’s magnetic north pole. The board is designed to use 3.3V power supply only. All these features make this board ideal for compensated compass, position detection, map rotation, pedometer, display orientation and many more.
MEMS sensors or Micro-Electro-Mechanical Systems are the sensors and actuators at the bare metal of embedded systems. MEMS are used for airbag systems, automatic door locks, security systems , earthquake detection, inkjet printers, kitchen appliances, and of course computer peripherals. In this blog we will explore the different ways you can use MEMS sensors.
