RF40315Ts Super Small Active RFID 40 Meters Transmitting Module


RF40315T-s Super Small Active RFID 40 Meters Transmitting Module ( Dimensions, 4.1 cm X 1.5 cm X 0.7 cm)

An unique 4 characters (A-Z, a-z, 0-9) will be sent out on every 2.5 seconds plus/minus 0.5 second. The matching receiver RF8315R can receive the ID within 40 meters although the RF power is very low. The transmitter will only turn on when ID is transmitting (< 0.01 second), as a result it will not cause data jam to other devices that are using the same frequency band.

Application Notes

This transmitter is not suitable for small in house application. The RF is bouncing inside small structure which will generate many fault signal. It is very difficult for the receiver to distinct whether the ID is correct or not.  It is an excellent choice for outdoor application.

The receiver RF8315R cannot receive ID sent by this transmitter within 2 meters.

The length of the antenna is very crucial to the overall design. The length of the antenna cannot be changed. The initial section of the antenna need to be perpendicular to the PCB and never bend toward to the battery.
