XTR-8LR-ENC --------------------------------------------------------------------------------------------------------------------------------------------------------------------- User manual TM XTR-8LR-ENC is a transceiver based on LoRa modulation able to guarantee very long range communication ( 8 Km line of sight ), high interference immunity , very high sensitivity and very low current consumption. Compared to standard modulation techniques, LoRa improves up to 20 dB the receiver sensitivity, allowing long distances by using low power transmission and very low consumption, inexpensive power supply circuits and reduced dimensions. XTR-8LR-ENC, to be paired with Aurel receiver XTR-8LR-DEC, allows to activate remote loads connected to the receiver. It embeds a secure encrypted RF communication. Its ideal when it has to activate and control loads at very long distance like, for example, in irrigation or alarms systems applications. The bidirectional communication allows to know if the XTR-8LR-DEC output has been activated. Module is available in tape&reel package for SMD assembly. Size is 35.5 x 18 x 2.4 mm. Main Features Applications Encrypted data transmission Agricolture Reduce dimensions ( 35.5x18x2.4 mm ) Irrigation Control ERP: max 10 mW Monitoring of photovoltaic plants Sensitivity -126dBm Industrial controls Power supply 3,0V SCADA Standard distance: 8000 m Tele-alarms Monitoring of instruments The technical features can change without forecasting.
