Product Description

The HD35AP4G is a wireless base unit designed for the HD35 wireless monitoring system, enabling remote communication between HD35 data loggers and cloud or PC-based monitoring platforms.

Based on the HD35APG architecture, this updated version supports modern 4G cellular communication instead of GSM/GPRS, providing faster and more reliable remote connectivity for environmental and industrial monitoring applications.

The unit receives data wirelessly from remote HD35 data loggers and can automatically transmit measurements, alarms, and status information via the cellular network to cloud servers, FTP, or e-mail systems. This makes it ideal for applications where Ethernet or Wi-Fi infrastructure is not available.

With built-in battery backup, flexible remote communication, and support for large wireless monitoring networks, the HD35AP4G is well suited for long-term remote deployments and IoT-based monitoring systems.
