Designed long range sensor monitoring system using RFID , sensors on these tags are of active and passive type which sends real-time sensor data upon request by the reader, and it could also store the sensor information over time by using data logging capabilities and sending the collected data when requested by the reader.
Sensor tags can have data logging capabilities and provide the ability to take scheduled sensor measurements The internal battery allows the sensor to turn on, take a measurement, store the data, and then turn back off. Because the tag is not constantly sending that information to the reader, it does not consume as much battery power like a beaconing active tag.
