LoRaWAN - Weather Station
The “WEATHER STATION LoRaWAN” is a versatile and rugged IoT (Internet of Things) device for continuous Weather Watching.
It is ideal for agriculture because it embeds the LoRa/LoRaWAN transmission technology, suitable to long range data transmission.
WEATHER STATION INTEGRATED SENSORS:
HARDWARE SENSORS
- Temperature
- Humidity
- Rain
- Wind Speed
- Wind Direction
SOFTWARE SENSORS
- Dew Point
- Wet Leaf

Connectivity
The SX1272 transceiver feature the LoRa™ long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. Using Semtech’s patented LoRa™ modulation technique SX1272 can achieve a sensitivity of over -137 dBm. The module use External antenna connector (50 Ω single-ended U.FL connector) or Ceramic antenna (868 MHz integrated antenna).
Power consumption:
Transmit mode:+14dBm 40 mA | Sleep mode: 3 μA
