An elongate, flexible sensor for sensing an electrically conductive liquid, such as water, has two flexible electrodes extending along the sensor and two flexible sleeves extending therealong and being attached adhesively to each other along the sensor. Each electrode is a ribbon made from a carbon-filled, silicone rubber material. Each sleeve extends around an associated one of the electrodes and is braided from a filamentary, polyester material so as to define multiple apertures enabling such a liquid reaching the sensor to pass through the sleeves so as to cause a short circuit between the electrodes.

In a system for monitoring trash compactors, each monitoring unit associated with a trash compactor comprises a transducer for sensing hydraulic pressure, for generating an analog signal from the sensed pressure, and for converting the analog signal to a frequency signal, and a microprocessor. The microprocessor compares pressure signal values generated from the frequency signal over timed intervals to a specified value indicative of a compaction. The microprocessor also compares the maximum pressure signal value generated therefrom, under certain conditions, to a threshold value indicative of the trash compactor having a substantially empty compactor and to a threshold value indicative of the trash compactor having a substantially full container. Whenever a specified, plural number of substantially full compactions have been determined, a modem sends a status signal to a computer at a remote location or a facsimile message to a facsimile machine at a remote location.
