Short description

Shelly BLU Distance is a smart battery-powered Bluetooth device equipped with an ultrasonic sensor for accurate distance and level measurement, including liquid level monitoring.

Main features

Distance or level measurement from 200 mm to 5 m via ultrasonic sensor
Level measurement of liquids or solids
Monitoring parking space occupancy
Automatic measurements at user-selectable intervals from 5 to 300 seconds
Automatic measurement at detected vibration
IP64 protection for durability and environmental resistance
Comes with protective sleeve and two nuts for mounting
Supports Bluetooth for flexible, low-latency control of your smart devices
Battery-powered for flexibility and uninterrupted operation
Supports local automation actions for independent operation
Support for Shelly Cloud and Shelly Smart Control app

Use cases

Environmental Monitoring (Liquid Level Monitoring in Tanks or Reservoirs) – The sensor continuously measures liquid levels in storage tanks and reservoirs, enabling automated refill alerts and preventing overflow or depletion.
Parking Management – The sensor detects vehicle presence in parking spots, providing real-time occupancy data for efficient parking management and space optimization.
Safety Systems (Door and Gate Automation) – By detecting obstacles in the path of automated doors and gates, the sensor prevents accidental collisions, ensuring enhanced safety in residential and commercial environments.
Smart Home Ecosystems (Garage Systems, liquid Tanks) – Integrated into a smart home system, the sensor helps automate garage door operations based on vehicle detection and monitors liquid tank levels to optimize household usage.

Main applications

Environmental monitoring (liquid levels in tanks or reservoirs)
Parking management (parking spot occupancy)
Smart home ecosystems (garage systems, storage tanks)
Safety systems (door and gate automation)
Industrial automation

Connectivity

Bluetooth Low Energy (BLE)

User interface

Inputs:

Push button:
- Single press: Reset the timer between measurements.
- Press 4 times: Enter pairing mode for 60 seconds.
- Press and hold for 30 seconds: Factory reset (only possible shortly after inserting the battery).

Outputs:

LED indication:
- LED flashes once on button press to show that the Device has accepted the user command and will immediately measure and broadcast the data.
- LED flashes fast after pressing the button 4 times to indicate pairing mode.
- LED flashes superfast on successful BLE/BT pairing for 5 seconds.

User options

User can configure the device with 7 ranges of operation. It is possible to set the device on full range mode or either set one or two measurement ranges to save battery by not checking all ranges. Valid values - from 1 to 7. Default mode is 7 - full range.

Range 1 - Close (200mm-450mm)
Range 2 - Mid (300mm - 3500mm)
Range 3 - Close and Mid (200mm - 3500mm)
Range 4 - Far (2500mm - 5000mm)
Range 5 - Close (200mm-450mm) and Far (2500mm - 5000mm)
Range 6 - Mid and Far (300mm - 5000mm)
Range 7 - Full range (200 mm - 5000 mm)

Modes of operation

Measurement on interval or vibration - Measurement is performed at fixed intervals. The default mode is 30 seconds, but can be adjusted (minimum 5, maximum 300 seconds). In addition, a button or vibration initiates a measurement earlier than the set interval. Then the new interval starts from the time of the last measurement, regardless of whether it is periodic or extraordinary by button or vibration.
