| The Sentry9000.TEMP module provides automated, wireless temperature monitoring of coolers, freezers and warmers. The sensors used are 418Mhz sensors and thermistors. A thermistor is a sensor with a cable that puts the sensor on the outside of a unit and the temperature prove on the inside. In addition, 900Mhz sensors and thermistors are used when a signal is impeded by walls or other constraints. The 900Mhz sensors send the radio signal at a stronger rate to the receiver.Data is presented on the district web site for all schools and on each school web site. The data shown is illustrated below. Long term data is available by query format and provides the basis for graphing and more. |
