TG462 / TG462S Weather Station Data Logger & 4G IoT Gateway

The TG462 / TG462S weather station data logger is an industrial IoT edge gateway designed to collect, store, process and transmit data from meteorological, agricultural, hydrological and environmental sensors.

With multiple RS485, RS232, analog, digital and Ethernet interfaces, the gateway can connect to weather sensors such as temperature and humidity sensors, wind speed and direction sensors, rain gauges, solar radiation sensors, soil sensors, water-level sensors and other compatible field instruments.

For remote monitoring, the TG462 series can be configured with cellular communication and optional Wi-Fi or GPS. It supports MQTT, TCP/UDP communication and Modbus gateway functions, allowing field measurements to be integrated with cloud platforms, SCADA systems or customer-owned servers according to the project architecture.

TG462 vs TG462S: Which Data Logger Should You Choose?

Weather Station Data Logger Interfaces

The TG462 series provides several industrial interfaces so that one gateway can acquire data from different types of sensors and instruments. This is particularly useful for modular automatic weather stations where RS485 sensors, analog transmitters, pulse/digital devices and control outputs may need to operate together.

Connect Weather Sensors to One Data Logger

A typical weather station uses several sensors with different measurement functions. The TG462 / TG462S can act as the central acquisition device, receiving data from wind, rainfall, temperature, humidity, pressure, radiation, water-level, soil and other compatible sensors.

Weather Sensors → RS485 / Analog / Digital Inputs → TG462 Data Logger → 4G / Ethernet / Wi-Fi → Remote Monitoring System

For RS485 Modbus sensors sharing the same communication bus, each sensor should use a unique Modbus address. Sensor power requirements, cable distance, communication baud rate and polling intervals should also be checked when designing a multi-sensor system.

4G, Ethernet and Optional Wi-Fi Connectivity

The gateway supports dual Ethernet interfaces and can be configured with cellular communication for remote monitoring. Optional Wi-Fi allows the gateway to operate in supported AP or Client modes.

LTE frequency bands differ by regional modem configuration. Provide the destination country and mobile operator requirements when requesting a quotation so the appropriate cellular version can be selected.

MQTT, TCP/UDP and Modbus Gateway Functions

The TG462 series supports multiple industrial networking functions for connecting field equipment with remote monitoring systems.

If the weather station must transmit a specific JSON structure, use a customer-defined topic, connect to a specific MQTT broker, communicate with an HTTPS/API endpoint or follow another private-server protocol, provide the server and data-format requirements before ordering. Custom software or configuration may be required depending on the project.

Local Data Storage

Local storage is important for unattended monitoring systems because weather and environmental data may need to be retained locally for later retrieval, analysis or network-failure handling.

If the project requires automatic offline buffering and retransmission after a network outage, preservation of records after a power restart, or a specific data-retention period, include these requirements when requesting the system configuration so the required software behavior can be confirmed.

TG462S 7-Inch Touchscreen Data Logger

The TG462S includes a 7-inch 800 × 480 TFT touch screen for local data visualization and field interaction. This is useful where operators need to view measurements or system status directly at the monitoring site without connecting a separate computer.

Optional GPS for Weather Station Location Data

GPS is available as an optional function. It can be useful for portable systems, distributed monitoring stations or projects where station coordinates need to be associated with measurement records.

If GPS latitude and longitude must be included in the same outgoing record as sensor measurements, specify the required data format and transmission protocol before ordering so the exact integration can be confirmed.

Edge Computing and Secondary Development

The TG462 series uses an OpenWrt-based software platform and supports secondary development for projects requiring custom data processing, protocol conversion or edge logic.

Power Supply and Sensor Power Outputs

For solar-powered weather stations, battery and solar-panel sizing should include the logger, cellular communication, all connected sensors and any external devices powered by the gateway. The communication current should be considered when estimating peak system consumption.

Relay Outputs and Local Control

The TG462 series provides four relay outputs rated up to 5A at the specified switching voltage. These outputs can be used as control contacts for compatible alarms, pumps, valves or external control circuits when appropriate logic is implemented.

The relay output should not automatically be treated as a power supply for the controlled device. External loads should use suitable power and protection according to the electrical design.

TG462 / TG462S Dimensions and Installation

The gateway uses a metal enclosure measuring approximately 228 × 122.5 × 38.2 mm. It can be wall-mounted or installed on a desktop / inside a suitable control cabinet.

The enclosure protection rating is IP30. Therefore, the logger should not be installed directly outdoors without protection. For weather stations, it should normally be installed inside a suitable weatherproof enclosure or cabinet.

Weather Station and IoT Applications

Although the TG462 series is well suited to automatic weather stations, the same multi-interface edge gateway can also be used for hydrology, agriculture, water quality, industrial monitoring and other IoT projects.

How to Select a Weather Station Data Logger

The most important selection question is not simply whether the logger has 4G. The interfaces, sensor quantity, data protocol, local storage, power supply and server requirements should be confirmed together.

TG462 / TG462S Data Logger FAQ

Q1. Can the TG462 connect to RS485 Modbus weather sensors?

A1. Yes. The gateway provides three RS485 interfaces and supports Modbus RTU communication for compatible field sensors.

Q2. Can it connect to 4–20mA sensors?

A2. Yes. The TG462 series provides eight 12-bit analog input channels that can support 4–20mA current or 0–5V voltage signals depending on the selected configuration.

Q3. What is the difference between TG462 and TG462S?

A3. TG462 is the standard IoT edge gateway, while TG462S adds a 7-inch touchscreen and uses 1 GB flash memory for applications requiring local visualization and interaction.

Q4. Does the data logger support 4G?

A4. Cellular communication is available according to the selected regional modem configuration. Provide the installation country so the required LTE bands can be checked.

Q5. Does the gateway support MQTT?

A5. Yes. MQTT is supported for compatible serial-to-network and IoT applications. The broker address, port, topic, authentication and required data format should be provided for private-server projects.
