Detection Capabilities: Can detect water or moisture present on floors, carpets and other surfaces. Provides a WET/DRY indication in software. Maximum reading rate: one reading every second Housing Dimensions: 8 cm (3.1") x 4 cm (1.6") x 2 cm (0.8") Housing Material: injection molded ABS thermoplastic Housing Colour: light gray Sensor type: Two penetrating gold plated pins and associated electronics that detect changes in conductance. Operating temperature range: 0 º C to +60 º C (32 º F to +140 º F) Communications cable: built-in 6 m (20 ft.) cable with RJ-45 plug connector Power source: Port-powered (RTS and DTR, both asserted). Power supply current drain: < 10 mA Communications Interface: RS232C using TX,RX,RTS,DTR and GND. One device per serial port. Maximum extension cable length: 305 m (1000 ft.) using recommended cable type. Low capacitance shielded cable or UTP is recommended. Communications Protocol: Sensorsoft Device Protocol, Version 2.0 (A detailed descripton of this protocol is included in the User Manual). Error control: 16 bit CRC (cyclic redundancy checking) for detection of communication errors between the device and host computer. Copyright © 1999-2003 Sensorsoft Corporation.
