WWD 150 SMART Water Detector - Battery Operated

WWD 150 Smart Water Detector – The Mobile Level Watcher with Smartphone Alert

No power? No problem – the WWD 150 from Elektrotechnik Schabus is completely wireless and smart. Equipped with a high-quality mini float switch, it detects water levels from about 4 cm (adjustable via mounting height) and instantly sends a push notification to your smartphone via the free Smart Life app – whether you’re on holiday or right next door.

A blue LED flashes on-site, and the battery status is always visible in the app. Powered by just 2 × AAA batteries (preferably rechargeable lithium batteries with USB‑C), with no cable clutter – 100% flexible. The perfect mobile protection for sump pits, heating oil tanks, cisterns, collection trays, or anywhere you want to know: “Is the water rising?”

The technology is typically robust – now fully mobile: the precise mini float switch works even with light dirt or oil. The 2.4 GHz WLAN connection is only required during setup; after that, operation runs locally and via the cloud. The LIYY cable is temporarily waterproof, flame retardant, and oil resistant. For vertical mounting, we recommend mounting bracket Art. No. 300787. Made in Germany – finally, a truly smart level detector that fits anywhere.

The WWD 150 is the smart bodyguard for all critical locations without a power socket. Holiday home owners, heating oil users, campers, and anyone with a sump pit or collection tray love it: simply place or mount it, connect via the app – and always know when the level rises, even if no one is on-site for months.
