Dragino WSC2-Compact-CS-GE, solar-powered NB-IoT/LTE-M transmitter for weather stations, without SIM card

The Dragino WSC2-Compact-CS is the cellular version of the autonomous WSC2-Compact weather station transmitter, featuring support for NB-IoT and LTE-M (CAT-M1). A solar panel and 3000 mAh Li-ion battery are integrated; measurements from climate, light, and rain sensors are transmitted directly via the cellular network without the need for a dedicated gateway. In addition, the WSC2-Compact-CS features GNSS and transmits its location, which facilitates the management of many distributed stations.

Main Features:

• NB-IoT and LTE-M (CAT-M1) in one device, no dedicated gateway required
• Integrated GNSS for location transmission
• Data transmission via MQTT, MQTTS, TCP, UDP, or CoAP, payload as JSON or HEX, multiple measurements per uplink possible
• Autonomous power supply via integrated solar panel and 3000 mAh Li-ion battery
• Parameterization and firmware updates via Bluetooth 5.1, additional parameterization via AT command or downlink, IP66 enclosure
