Smart lock with Bluetooth & home router connectivity
The smart lock is a rapidly growing trend in smart home appliances. Users can control smart locks by using fingerprints, Near Field Communication (NFC), capacitive touch, or low power Bluetooth® communication. With a low power design, NarrowBand-Internet of Things (NB-IoT) is also an option. As the RX130 MCU has integrated capacitive touch capabilities, it enables smaller board design and reduced cost. For advanced systems with more sophisticated fingerprint modules, an upgrade to the RX651 is an option for the algorithm design.
This solution can support Bluetooth communication with mobile or smart home routers. Additionally, the NB-IoT modem can directly support WLAN and directly send an alarm condition to the cloud.
Key features:
- Highly integrated RX130 with built-in capacitive touch
- Low power design for extended battery life
- Shock sensor monitoring to alert for potential tampering and break-ins
