NH-800T specification
NH-800T is the best wireless data transmitter and receiver with highest performance, largest range under the low power at present. It can transmit the data far to 5 kilometers in the city at the sensitivity of -148dBm . The excellent performance has exceeded all GFSK modules on the sensitivity, stability and immunity of interference, because of the newest technologies including the spread spectrum, auto-spread-spectrum logical arithmetic, the high-speed STM MCU, and forward CRC correction.
Users can modify all configurations like serial port baud, the carrier frequency, the spread-spectrum factor, and ratio of effective data, the bandwidth by the principal computer software offered by our engineers.
II. NH-800T feature
1. Middle class power 100mW, 7 level cost down, high quality and stability
2. GSF Modulation, half-duplex mode, transmitting and receiving in air, automatically connect and control
3. Free frequency band: ISM band like 315/433/490/915MHz
4. High capability of immunity from interference, low rate of code error, LoRa modulation,the forward correct code. Hopping frequency and Spread Spectrum strengthen the capacity of anti-interference.
5. Receiver sensitivity up to -148dBm, and far to 3500 meters, even 4000 meters in the open air when the antenna height is 2 meters.
6. Transmitting current less of 120mA, Output power up to 20dBm
7. Receiving current 30mA (25mA optional), sleeping current less 10uA (TTL user-defined)
8. Standard configuration with 32 channels can meet all combinatorial requirements users need,
capacity of channel extension.
9. Communication baud rate 1.2kbps- 115.2kpbs can be set by users flexibly.
10. Easy to use, automatically transfer the protocols and switch.
11. Voltage ranges from 4.5V to 5.5V, 3.0V-3.6V is optional
12. The carrier frequency band is flexible to set by the software in PC.
13. TTL, RS232,RS485,USB2.0 is optional
14.The factor of Spread spectrum is optional by software in PC
15. User is easy to use the USART interface to access the module without modification the RF software.
17.Support the waking up in the ultra remote, and acknowledges with AUX in order to decrease
the power consumption by user
18. Support the serial port to wake up the module, no time delay
19. CAD detects the signal of LoRa avoid the wrong wakening
