The LSM9DS1 is a versatile, motion-sensing system-in-a-chip. It houses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer – nine degrees of freedom (9DOF) in a single IC! The LSM9DS1 is equipped with a digital interface, but even that is flexible: it supports both I2C and SPI, so you’ll be hard-pressed to find a microcontroller it doesn’t...

The GY-362 ADXL362 Sensor Module is a high-precision accelerometer module designed for a wide range of motion sensing applications. Powered by Analog Devices' ADXL362, this module offers ultra-low power consumption, exceptional accuracy, and versatile functionality.

The GY-51 LSM303DLH chip has an accelerometer, magnetometer, A / D converters and signal conditioning circuit integrated. Still, the communication to the processor is done through the I2C bus. Thus only one chip is required to achieve a six-axis data detection and output. The LSM303DLH requires very little peripheral devices.

The US1881 is an integrated Hall-Effect latched sensor. That's nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A Hall-Effect sensor is much smaller, but can handle less current...

This AT407 basic tilt switch can easily be used to detect orientation. Inside the can is a ball that make contact with the pins when the case is upright. Tilt the case over and the balls don't touch, thus not making a connection. There are numerous uses for these basic sensors, but keep in mind you might need to use some debouncing code, as the sensor...
