What does the Shelly BLU Distance measure?

The Shelly BLU Distance measures distance using the ultrasonic principle over a 200-5000 mm range and turns the value into liquid level or object presence data.

How long does the battery last and what type is it?

The sensor uses a 3.6 V, 2700 mAh LISOC 14505 battery with up to 4 years of autonomy depending on the configured measurement interval.

Which protocol does it use and what is the range?

It uses Bluetooth 5 (BLE) in the 2402-2480 MHz band, with a range of up to 10 m indoors and 30 m outdoors.

Can I use the sensor for a water tank?

Yes, BLU Distance suits level monitoring in tanks and cisterns; mount it above the liquid surface, not submerged, since protection is IP64.

What is the measurement accuracy?

Accuracy is +/- 2 cm in the 20-200 cm range and +/- 1% for distances above 200 cm.

Is there a warranty and delivery in Moldova?

Yes, CasaSmart offers a 24-month warranty and delivery across Moldova, including Chisinau, plus free consultation on range configuration.

Where it works

Use cases

A household in the Chisinau suburbs gets a notification when the garden water tank drops below a set threshold.

Continuously monitors liquid level in a tank or cistern and sends an alert when it is time to refill.

In a residential complex in Moldova the sensor signals whether the assigned parking bay is occupied.

Identifies a vehicle present in a parking bay based on measured distance.

At the entrance of a private house the sensor stops the gate when an obstacle enters the measuring range.

Detects obstacles in the path of a gate or automatic door to prevent collisions.
