Overcome underground RF propagation challenges
Heavy cast-iron manhole covers attenuate wireless signals. Position LoRaWAN antennas strategically beneath surface vents or select composite/perforated covers to achieve reliable 2–5 km city transmission.
Manage aggressive sewer atmospheres
Manholes contain humidity, hydrogen sulfide (H2S), methane, and road salt wash. Specify IP67/IP68 enclosures with hydrophobic membranes to prevent internal condensation.
Configure multi-stage rising water alert thresholds
Program the sensor to switch from standard 30-minute intervals to continuous 2-minute rapid updates when water level crosses warning thresholds.
Integrate with municipal SCADA and emergency teams
Forward real-time overflow alarms via webhooks and SMS to drainage maintenance crews before surface flooding occurs.
