This hands-on describes how to configure FXLS8974CF accelerometer available on-board or magnetic switch sensor NMH1000 using Hall Switch 3 click expansion board on FRDM-MCXW71 to autonomously detect tampering/theft/abuse on device using low-power motion/magnetic wakeup feature and transmit ALERT message via BLE wireless UART.
There are many applications where user would like to detect and be informed about damage/abuse or act of theft on their high value/secure assets at home and/or workplace environment. Target applications include Smart meters tampering, home security, Safe box/locker tampering, Personal medical device abuse, personal laptop/tablets tamper/theft, Warehouse theft detection, machine tampering, Door open/close detection etc.
