ABSTRACT:
A wireless wastewater system monitoring apparatus generally comprising a processor/transceiver unit, housed within a synthetic protective enclosure formed outside of the wastewater system, and a fluid level sensor configured to send an overflow signal to the processor/transceiver unit when an overflow condition in the wastewater system is detected. The processor/transceiver unit is configured with at least one microprocessor wired between the sensor and a power supply and with a transceiver so as to detect the overflow signal from the sensor and, in response, transmit a wireless alarm signal. The processor/transceiver unit is further configured such that only a portion of its circuitry is constantly powered so as to continuously monitor the sensor, while the remainder of its circuitry, including the transceiver, is only powered and a wireless signal sent from the unit when an overflow condition is detected or a routine status-check is being conducted.
