Dragino WSC2-Compact-LS, solar-powered LoRaWAN transmitter for weather stations, EU868

The Dragino WSC2-Compact-LS is the third-generation transmitter for the Dragino weather station and operates completely autonomously: the solar panel and 3000 mAh Li-ion battery are integrated, eliminating the need for an external solar supply with an MPPT charge controller and control cabinet. It reads data from the DR-THP-6P 3-in-1 climate sensor, the DR-IL-6P light sensor, and the DR-RG-6P tipping bucket rain gauge, transmitting the measurements via LoRaWAN to any network server. Optionally, additional Dragino sensors such as anemometers, radiation sensors, or soil sensors can be added via RS485.

Key features:

• LoRaWAN 1.0.3 Class A, compatible with standard LoRaWAN gateways and network servers like TTN or ChirpStack
• Autonomous power supply via integrated solar panel and 3000 mAh Li-ion battery, no external power supply required
• Connection for 3-in-1 climate sensor, light sensor, and tipping bucket rain gauge, optionally expandable with RS485 sensors (wind, global radiation, PAR, climate, soil)
• Parameterization via Bluetooth 5.1, AT commands, or LoRaWAN downlink, wireless firmware update via OTA
• IP66 enclosure for permanent outdoor use
