Shelly BLU Distance - Bluetooth Smart Distance (ToF) Sensor, Level and Presence Monitoring

TheShelly BLU Distance is a high precision Time-of-Flight (ToF) based sensor designed to measure the distance to an object or surface with millimetre accuracy. Utilising Bluetooth protocol, this compact device is the ideal solution for monitoring liquid levels in tanks, measuring distances in automation projects or detecting the presence of objects in specific areas. It is part of the Shelly BLU range, offering exceptional battery life and fast integration into the Shelly ecosystem.

Key Selling Points

• High Accuracy ToF Technology: Measures distance by calculating the time it takes for a light signal (invisible laser) to bounce off an object. This method is much more accurate than conventional ultrasonic sensors and is unaffected by ambient sounds.

• Ultra Low Power Consumption: Operates on a standard battery, which can last up to 2-3 years thanks to the efficiency of the Bluetooth Low Energy (BLE) protocol.

• Liquid/Solids Level Monitoring: Ideal for remotely checking the water level in tanks, heating pellet stock or oil volume, preventing accidental emptying of tanks.

• Cable-Free Installation: As a completely wireless device, it can be mounted in hard-to-reach places without the need for holes or electrical wiring runs.

• Security and Encryption: Supports Shelly security mode (AES encryption), ensuring that data transmitted to your hub is protected against eavesdropping.

• Integration into Complex Scenarios: Can trigger automated actions via script in Shelly Plus/Pro devices (acting as a gateway), allowing automation of pumps or alert systems.

Smart Automation Examples

1. Water Tank Management: Install Shelly BLU Distance on the tank lid. When the water level drops below 8 inches, the sensor sends a command to a Shelly Pro 1 to automatically start the fill pump.

2. Garage Parking Sensor: Mounts the sensor on the front wall of the garage. Programme a scenario where an LED strip turns red when the distance between the sensor and the car's bumper is less than 30cm.

3. Lid Open Detection: Sets an alert on your smartphone if the sensor detects that the distance to the lid of the smart bin or storage container has changed, indicating that it has been left open.
