433 Mhz, Battery Operated, 16 bit Unique ID
This is an active RFID Transmitter tag which transmits 16 bit unique ID on 433 Mhz frequency giving range of around 25 meters.
It is powered by its PCB mounted 3V battery at bottom. Total of 64 such active RFID transmitter tag can co-exist with each other in same premises each automatically occupying its own time slot without interfering with each other.
The RF receiver for listening to these tags can be bought separately from us which gives out serial data containing 16 bit unique ID for each tag when detected in its range.
The tag is active in the sense it is powered by battery and gives long range of operation as compared to passive tags. There a jumper for ON/OFF of the tag. When the jumper is moved to ON position the tag is connected to battery. When it is powered ON it transmits 16 bit unique code ID on 433 Mhz frequency every 6 seconds. The transmission time for the signal is 100ms after which it goes to sleep thus saving battery. After 6 second it wakes up again automatically and transmits its unique 16 bit code. This keeps going on as long as the tag is powered ON. The battery life is around 2 months with continuous on position. Antenna in built on the PCB itself making the unit compact and hand held. There can be up to 64 active tags operating in same premises.
