It is designed with industry standards, robust and stable. IP66 rated, waterproof and dustproof, it is highly suitable for long-term remote environmental monitoring in outdoor application scenarios. Sensor Hub Data Logger is an easy-to-deploy 4G cellular station. It uses the MODBUS-RTU RS485 protocol to communicate with sensors and is able to collect various sensor data simultaneously. Sensor Hub consists of 4 RS485 data channels. With extension hubs / RS485 splitters, it can connect with a maximum of 32 sensors at one time. The data is collected and sent to the cloud (either to the SenseCAP server or the client's private server) via 4G/3G/2G (as shown below). Designed with industry standards and IP66 rated, Sensor Hub is suitable for outdoor and harsh environments, resistant from UV, rain, and dust, etc. GNSS is embedded for location tracking. Sensor Hub is also equipped with 10MB onboard memory, to store more than 700,000 measurements locally in case of a bad connection. For the DC-only version, if there is a power outage, Sensor Hub won't be able to store the data.you can also consider using it with a solar system (to be purchased separately.) Designed with an easy-to-deploy mindset, Sensor Hub can be deployed and set up within a few minutes. It is fit for both pole and wall mount.
