Detailed Product Description

Data Rf modules JZ861,433MHZ,5V,8channels,used for home automation,sports traing &competition and so on .

Technical specification of JZ861:

1.Power and receiving sensitivity
The transmission power is <10mW, Receiving sensitivity: -110dbm,
Transmission current<35mA, Receiving current<10mA, sleeping current <1uA.
2. Modulation mode and Frequency 
Modulation mode: FSK, Frequency: 433mhz. Also, capable of 315mhz, 868mhz and 915mhz.
3. High anti- interference and low BER(Bit error Rate)
Based on the FSK modulation mode, it adopts the efficient communication protocol. 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 isBER=10-3/1200bps >150m when the antenna height is greater than 100m (BER=10-3/9600bps).
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- channel
The standard JZ861 configuration provides 8 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. JZ861 will complete the other operations automatically, such as transmission/receiving conversion in the air, control, etc.
9. 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.
10. Watchdog monitor
Watchdog monitors the inner function, it changes the traditional product structure and also improve the reliability of our modules.
