Description

The Shelly BLU Distance performs continuous ultrasonic distance measurements every 30 seconds, delivering precision within 1 mm across a range of 25 cm to 3.5 m. These readings are then transmitted to your Shelly system, or any compatible smart‑device network, via both Bluetooth and Zigbee, allowing it to slot easily into mixed‑protocol environments.

Its lithium battery is housed in a specially designed protective casing that prevents deformation in challenging temperatures between 0 °C and 45 °C, ensuring consistent measurement accuracy. Depending on usage, the device can operate for two to three years on a single battery. Alongside distance sensing, the BLU Distance also includes an integrated vibration sensor, sending immediate alerts to your network whenever movement or disturbance is detected.
