Sensor Wireless Range

Wireless range is affected by distance, walls, radio interference, antenna orientation, water, crowds, and metal. Rated line-of-sight values assume open space with no obstacles.

BLE sensors

The rated line-of-sight range for BLE MOCREO sensors is about 40 m / 131 ft. Real-world range is usually shorter.

1. Water and objects containing water, including food and people, absorb Bluetooth signals effectively.
2. Refrigerators, freezers, walls, and long distances can reduce reliability.
3. Try different hub antenna orientations and sensor placements.
4. Change one condition at a time and observe whether communication improves.

Zigbee sensors

The rated line-of-sight range for Zigbee MOCREO sensors is about 100 m / 325 ft. Real-world range is usually shorter.

1. Metal and objects containing metal absorb or block Zigbee signals effectively.
2. Walls, long distances, and interference can reduce reliability.
3. Try different hub antenna orientations and sensor placements.
4. Change one condition at a time and observe whether communication improves.

Placement tip

If communication is intermittent, the system is near the edge of reliable signal. A small placement improvement can make the connection stable.
