Smart LTE GPS Padlock
A battery-powered padlock with remote access, GPS location reporting, LTE/eSIM connectivity and a local keypad.
Overview
The Smart Padlock combines remote access, location reporting and a local keypad in a battery-powered device. Users can operate it through desktop or mobile software, or enter an access code directly on the lock.
- Connected Devices
- LTE
- GPS
- eSIM
- Access Control
LTE connectivity and an eSIM provide the cellular connection. GPS supplies location information, while the electronics also include flash memory and current monitoring.
Challenge
Combine local and remote lock operation with cellular status reporting in a compact battery-powered design. The embedded system needs to connect access commands, device state and location information across its physical and remote interfaces.
What We Did
HTS developed the hardware, embedded firmware, and mobile/cloud integration for the connected padlock. The scope brought together access control, cellular communication, positioning, local interfaces and device monitoring.
System
- Local interaction
- The keypad provides code-based operation at the device.
- Embedded control
- The Nordic cellular IoT platform coordinates the device functions, supported by flash storage and current sensing.
- Remote connection
- LTE/eSIM connects the padlock to software used for control and status information; GPS provides location data.
