RF40315T-x Active RFID 40 Meters Transmitting Module


RF40315T-x Active RFID 40 Meters Transmitting Module ( Dimensions, 5.9 cm X 2.6 cm X 1.5 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,  RF40315T-x Active RFID 40 Meters transmitting module

  • Vehicle tracking
  • Moving object tracking

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.

It has no problem for object moving no faster than 25 km. There may not be100% reliable if moving faster than 25 km.

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.

The left most pin is (9V~40V), center pin is 6V and the right most pin is Ground.

Warning - The 6V input is not regulated. If you apply 6.9V or above the microcontroller will be permanent damaged.
