Product Information
- Working frequency band: 410~525MHz Transmitting power: 22dBm (max ultra-low receiving current: 5mA ultra-high receiving sensitivity: -137dBm (@250bps) ultra-long effective communication distance: 5Km@250bps (urban highway environment, non-wild environment)
- High confidentiality, using LoRa modulation method, traditional devices cannot capture and analyze it. High concealment, and normal communication can still be performed when the average in-band power is lower than the noise floor
- Use spread spectrum technology to communicate, the same urban and industrial application environment, the performance is better than the traditional modulation methods FSK, GFSK, PSK, ASK, OOK, etc.) working with radio frequency products, in harsh noise environments (in electric meters, beside motors, etc.) (Near strong interference sources, elevator shafts, mines, basements and other natural shielding environments) have obvious advantages
- Working voltage: 2.0~3.7V industrial-grade crystal oscillator, suitable for industrial sites with complex environments, SPI communication interface, can be directly connected to various single-chip computers, and software programming is very convenient
- Adopting LoRa modulation method, compatible with and supporting FSK at the same time, GFSK traditional modulation method supports frequency hopping (FHSS), combined with LoRa spread spectrum technology, can achieve superior communication concealment and comprehensiveness
