Description

The MOKO Smart S03D is a wireless, battery-powered contact sensor engineered for security and automation systems. Its core sensing element is a Hall effect sensor paired with a magnet, which triggers a state change when the gap between them exceeds 25mm, reliably detecting door or window openings and closings. This digital status is transmitted via Bluetooth 4.2 Low Energy to a paired gateway or smartphone app, enabling real-time push notifications and remote monitoring.

Designed for long-term deployment, the sensor features a robust IPX4-rated housing that protects against water splashes, making it suitable for use in bathrooms, garages, or other potentially damp areas. Its ultra-low-power BLE radio and optimized firmware are powered by a user-replaceable 2600mAh lithium battery, engineered to deliver years of maintenance-free service under typical usage patterns, significantly reducing the total cost of ownership.

Key Features

  • Bluetooth 4.2 Low Energy (BLE) wireless interface for energy-efficient, long-range communication up to 150 meters line-of-sight.
  • High-sensitivity Hall effect magnetic sensor ensures accurate contact detection with a precise 25mm activation gap.
  • Extended operational lifespan powered by a large-capacity 2600mAh user-replaceable lithium battery.
  • IPX4 waterproof construction provides reliable protection against incidental water splashes from any direction.
  • Compact and lightweight form factor (80mm x 25mm) facilitates discreet installation on doors, windows, or cabinets.
  • Dual mounting options include a strong 3M VHB adhesive pad and provisions for screw-based installation for permanent setups.
  • Wide operating temperature range from -20°C to +60°C ensures stable performance in diverse climatic conditions.
  • Smart home ecosystem integration enables automated scene triggers based on door/window status changes.

Applications

  • Residential and commercial security systems for monitoring door and window entry points.
  • Smart home automation to trigger lights, HVAC, or alarms based on occupancy or access events.
  • Asset tracking and inventory management in warehouses by monitoring cabinet or storage room access.
  • Elderly or patient care monitoring to alert caregivers to unusual movement patterns or potential wandering.
  • Energy management systems to automate climate control by detecting open windows or doors.

Frequently Asked Questions

What is the wireless communication range of the MOKO Smart S03D sensor?

The sensor utilizes Bluetooth Low Energy (BLE 4.2) and has a maximum open-space transmission range of up to 150 meters (approximately 492 feet). Actual range in real-world environments will be reduced by walls, metal obstructions, and other sources of RF interference. For reliable operation, it is recommended to test the signal strength at the intended installation point.

How does the sensor detect if a door or window is open?

The S03D employs a Hall effect magnetic sensor. A separate magnet is installed on the moving part (door/window), while the sensor unit is installed on the fixed frame. When the door is closed, the magnet is within 25mm of the sensor, keeping the circuit in one state. Opening the door breaks this magnetic field, triggering a state change that is reported via BLE to your connected app or gateway.

What is the expected battery life and how do I replace it?

Powered by a 2600mAh user-replaceable lithium battery, the sensor is designed for up to 8 years of operation under typical usage (several events per day). The battery compartment is accessible on the unit. When the battery is low, you will receive a notification via the mobile app. Simply open the compartment, swap the old battery for a new CR2477 or equivalent 3V lithium cell, and the sensor will resume normal operation.

Is this sensor suitable for outdoor use or in damp areas like a bathroom?

With an IPX4 splash-proof rating, the S03D is protected against water splashes from any direction, making it suitable for use in bathrooms, garages, or under eaves where it is not directly exposed to sustained rainfall or submersion. It is not rated for full outdoor exposure or submersion (IP67/IP68). The operating temperature range of -20°C to +60°C supports use in unheated spaces like sheds or warehouses.
