Can nRf51822 be activated by vibrations?

My question is can the beacon be activated by someone shaking it and receive a notification via Bluetooth? If so what is the range it would have? If not can an additional sensor be added to achieve this effect? Understanding that additional equipment maybe be needed. Student in classroom setting for project.

  • Yes, easily done, we've done something similar. Couple your nRF with an accelerometer such as an MPU6500 (about $5) through TWI. Use Port mode for low power interrupt and it consumes only micro amps. Range could be up to 100 meters depending on antenna layout/tuning. There is sample code put out by the Nordic guys that can get you up and running with the MPU6500 pretty quick.
