אלו הנתונים של המRF9315R Active RFID Receiver Module with RSSI ( Dimensions, 4.5cm X 6.5 cm X 1.5 cm )
The RF9315R active RFID receiver module receives data sent from RF8315T modules. This low-cost receiver module requires no external power supply (some pc or notebook may require external 9V power input). Data received will be sent to RS232 com port. Standard communication software such as Hyperterninal can read the data. Custom program can read data from com port for system integration or application development.
Key Benefits
- Plug and play. No need to send command to control the receiver
- Can read data within 8 meters with build in RF8315T antenna. If RF8315Tantenna changed to 9" wire the effective radius can be 14 meters
- RSSI data will be reported that can be used to determine the object is moving toward or away from the receiver
- No power input is required for most desktop PC
- Superheterodyne design for maximum stability
- Reverse power input protection
