BOM price: 19 USD

Realization time: 4 weeks

As name it self states this is a small BLE enabled keychain with inductive custom built inductive charging mechanism. The device once paired with mobile phone tracks the distance from mobile phone. If the mobile phone distance from keychain is above the predefined threshold the sound alarm is initiated.

Requirements:

• BLE interface for device configuration
• BLE signal monitoring
• Inductive battery charging
• Audio signal for out of range indication
• Small and compact size

Major components:

• nRF52832 BLE SoC
