JZ871 GFSK 433/868/915Mhz Wireless Adapter/Data Transmission/Tranffic Light Control Modem

Place of Origin: Guangdong China (Mainland) Brand Name: Jizhuo Model Number: JZ871 Size: 44*27*8mm Case: naked Weight: 20g Packaging & Delivery Packaging Detail: Standard package for export Delivery Detail: 1-3 days after the receipt of the payment Specifications Low Power Data RF Module 100mw, range is 1000m,433/868/915mhz, 9600bps. users can set the baudrate according to the request Technical specification of JZ871:Low Power Data RF ModuleSerial numberItemParameterNote1Modulation modeGFSK 2Work frequency433MHZ 868/915mhz is possible3Transmission power100MW <10mW4Transmitting current<100mA 35mA5Receiving current<20mA 30mA6.Sleeping current1uA 7Receiving sensitivity-121dbm(1200bps) 8Channel amount16 channelUser setting9Working temperature-20+65°C10Working humidity10%~90%(relative humidity without condensation) 11Antenna impedance:50 12Power supply+5V 13Dimension44mm×27mm×8mm 14InterfaceTTL, RS232, RS485user can choose15Reliable transmit distance800m Features:1.Power and receiving sensitivity a. Transmission power <1W, TX current<100mA, RX current<20mA,b. Transmission power<10mW, TX current<35mA, RX current<30mA,High receiving sensitivity: -121dbm.2. Modulation mode and Frequency Modulation mode: GFSK, Frequency: 424-448MHZ. Also, 868mhz and 915mhz is possible.3. High anti- interference and low BER(Bit error Rate)Based on the GFSK modulation mode, the high- efficiency forward error correction channel encoding technology is used to enhance datas resistance to both burst interference and random interference and the actual bit error rate of 10-5 ~ 10-6 can be achieved when channel bit error rate is 10-2.4. Long transmission distance Within the range of visibility, the reliable distance is >800m ().5. Transparent data transmission Transparent data interface is offered to suit any standard or nonstandard user protocol. Any false data generated in the air can be filtrated automatically (What has been received is exactly what has been transmitted). The change time between receiving and sending is <10ms. 6. Multi- channelThe standard JZ871 configuration provides 16 channels to meet the multiple communication combination mode of the user.7. High speed wireless communication and Large data buffer zone     When the RF baudrate is bigger than COM baudrate, allowing to transmit unlimited length data at one time, when the RF baudrate is smaller or equal to the COMs, allowing the transmission of 255 Bytes data . 8. Intelligent data control and the user doesnt need to prepare excessive programs Even for semi duplex communication, the user doesnt need to prepare excessive programs, only receiving/transmitting the data from the interface. JZ871 will complete the other operations automatically, such as transmission/receiving conversion in the air, control, etc.9. Low power consumption When transmission power is 1W, The Transmission current<35mA , Receiving current<30mA,sleeping current <1uA. 10. High reliability, small and light Single chip radio - frequency integrated circuit and single chip MCU are used for lessened peripheral circuits, high reliability, and low failure rate. 11. Watchdog monitor Watchdog monitors the inner function, it changes the traditional product structure and also improve the reliability of our modules.
