SenseCAP 4G Data Logger with RS485 and DC Input

The SenseCAP 4G Data Logger is a powerful industrial 4G data station that uses the MODBUS-RTU RS485 protocol to communicate with sensors and simultaneously collect various sensor data. It is IP66 certified, waterproof, and dustproof, making it suitable for long-term and reliable outdoor applications, such as in smart agriculture, smart weather stations, and smart city projects. This data logger supports the collection and storage of environmental data even with poor connection and automatically uploads the data once the network connection is restored. It is equipped with a built-in GPS function and allows remote maintenance and updates. The power supply can be either DC or an optional solar system. Installation and commissioning are simple and do not require technical knowledge, making the Sensor Hub ready for use within minutes.
