4-Channel LoRaWAN Ultrasonic Distance Sensor

One LoRaWAN node that reads up to four ultrasonic distance probes. A single device can monitor several tanks, bins or bays side by side, cutting the number of radios, batteries and network registrations needed on a site. Low power consumption supports long battery operation in the field. Typical uses include rows of water or chemical tanks, waste-bin clusters, sumps and parking bays. On the NARA platform each channel appears as its own fill level or occupancy reading, with individual thresholds and alerts.
