Accuracy ±10% Resolution 0.1 LoRaWAN Frequency Note: No Frequency limitation. Weather stations can be switched to other frequency plans at any time. S2120 is manufactured to support the universal frequency plan from 863MHz ~928MHz in one SKU. That is to say, it can support the frequency plans below: Frequency Plan Common Name Sub-band EU863-870 EU868 ___ US902-928 US915 Sub-band from 1 to 8 AU915-928 AU915 Sub-band from 1 to 8 AS923 AS923 AS923_1, AS923_2, AS923_3, AS923_4 IN865-867 IN865 ___ KR920-923 KR920 ___ RU864-867 RU864 ___ The frequency plan setting is none by default and it will not transmit RF signal until it has been set by App via Bluetooth at the first power-up. And it can be changed to other frequency plans at any time.

Powerful SenseCAP Mate App: data visualization and remote device management Compatibility with Multiple Networks and Platforms: easily integrates with existing worldwide LoRaWAN networks How to Select Gateway: LoRaWAN network coverage is required when using sensors, there are two LoRaWAN network options. Option 1: Sensors work in areas covered by Helium Network (Check on Helium Explorer). Option 2: Sensors work in a standard LoRaWAN network, like The Things Network, Loriot, Chirpstack, etc (Check out the SenseCAP Gateway series). We highly recommend that you use our SenseCAP M2 Multi-Platform LoRaWAN Gateway, which is a standard LoRaWAN gateway that supports connection to different network servers, its cost-effectiveness becomes a standout advantage, especially when building your private LoRaWAN network.
