Envco – Environmental Equipment

Grid-like, resistance-type sensor mimics moisture on vegetation from 0 (dry) to 15 (wet). Up to two sensors per logger.

The sensor is a circuit board with interlacing gold-plated fingers. Condensation on the sensor lowers the resistance between the fingers, which is measured by a datalogger.

The sensor includes a 6 foot cable which is plugged into port on a Model WatchDog Data Logger. Once the sensor is positioned in a representative"micro-climate", plug the cable into the WatchDog external channel to log temperture data.To connect an external sensor to the logger, plug the sensor cable into the logger port that has been programmed for that particular sensor. If the sensor is not connected, the message "sensor error" will appear on the LCD display for the respective logger port until the sensor is connected.
