A wireless door/window sensor that detects openings and closings using an internal magnetic reed switch and reports events to a Mobilelock alarm unit via Bluetooth Low Energy (BLE). The unit includes a magnet, mounting hardware, a replaceable lithium battery, and an internal terminal block for adding a normally closed (N.C.) external sensor. It also provides configurable alerts for temperature, tamper, and low battery.

Project Ideas

Business

Trailer and Mobile Asset Security Kit

Bundle a Mobilelock unit with multiple sensors to secure trailer doors, job boxes, and ramp gates. The system logs open/close events, warns on tampering, and supports up to 10 BLE sensors per hub for multi-door setups. Offer installation and monthly monitoring as a service for contractors, landscapers, and delivery operators.


Cold Chain Compliance for Small Vendors

Deploy sensors on fridges/freezers and set high/low temperature alerts to protect perishable goods in cafes, food trucks, and floral shops. Door event history helps correlate temperature excursions with access. Provide reports and alert tuning as a subscription service.


Short‑Term Rental Owner Locker Protection

Install sensors on owner closets, supply cabinets, and exterior storage at vacation rentals. Hosts get immediate alerts if restricted spaces are opened, plus tamper notifications. Package with a simple onboarding guide and remote support; one Mobilelock hub can manage multiple sensors per property.


Pop‑Up Retail Display Security

Secure display cases and stock totes at markets or trade shows. The compact sensors attach with the included bracket and detect unauthorized openings, while tamper alerts flag attempts to remove them. Offer a rental kit with pre-paired hubs and rapid setup for event vendors.


Construction Site Container & Crib Monitor

Equip shipping containers, material sheds, and tool cribs with sensors on doors and hatches. Add an external normally closed contact (e.g., a heavy-duty contact or floor pressure mat) via the terminal block for broader coverage. Offer deployment, weekly health checks (battery/tamper), and incident reporting to GCs.

Creative

Greenhouse Vent & Frost Guardian

Mount the sensor on a greenhouse vent window to track openings and closings, and enable high/low temperature alerts to protect plants from frost or heat stress. Place the Mobilelock unit in the greenhouse or nearby shed (within ~100 ft). Use up to 10 sensors to cover multiple vents and doors, and get notified if someone tampers with a sensor.


Backyard Gate Pet Watcher

Install on a backyard gate so you get an instant alert when the gate is opened, helping prevent escapes. The tamper alert discourages disabling, and the replaceable CR123 battery keeps it low-maintenance for seasonal use. If the gate is far from the house, position the Mobilelock hub centrally to stay within BLE range.


Freezer/Homebrew Fridge Safeguard

Attach the sensor to a freezer or fermentation fridge door and set a high-temperature alert to catch warming events that indicate a door left ajar or a failing compressor. Door open/close events provide an activity log, and the low-battery alert ensures long-term reliability.


Workshop Tool Cabinet Sentry

Use the magnetic reed switch on a tool chest or cabinet to log access and receive alerts after hours. For specialty storage (e.g., a chemical locker), add a normally closed external sensor like a second contact on an interior drawer using the terminal block to expand coverage.


Puzzle Box/Secret Compartment Notifier

Create a hidden compartment or puzzle box that sends an alert when opened. Chain multiple normally closed contacts in series to the terminal block so only a specific sequence of doors/lids produces the expected single open event, adding a fun logic element to the build.
