Hardware Configuration Details

The automatic rain measurement station includes the main equipment: Rain measurement sensor, data storage unit (datalogger), communication modem, technical cabinet, battery, power converter, lightning protection device, pole, and installation accessories;
All sensors are connected to the datalogger. Here, the measured data is processed, analyzed, and transmitted to the server via GSM mobile network through a GSM modem.
The datalogger has the capability to measure and store large amounts of data;
The system has high integration capability, making it easy to upgrade, expand the network, or be compatible with other existing systems;
The technical cabinet is made of durable materials and is specially designed for use in natural environments, resistant to sun and rain. In addition, the technical cabinet is designed for good heat insulation, with cable entry holes sealed properly to avoid moisture and prevent insects from entering;
The technical cabinet is used to install the datalogger, GSM modem, charge controller, battery, and surge protection device.
In particular, the system ensures extremely low power consumption, suitable for remotely controlled automatic stations, operating independently.

Technical Specifications of Main Devices

1. Rain Sensor – Lufft Rain Gauge WTB100

The sensor is a tipping bucket type with a non-contact magnetic switch.
Key features of the product: The resolution can be switched from 0.2 to 0.5 with a funnel area reduction ring and can be connected to any other WS sensor from Lufft.
Interface: Pulse output (reed contact)
The sensor is made of high-durability synthetic plastic material.
The tipping bucket sensor is easy to use.
It can be connected to any WS sensor without the need for integrated rain measurement.
The resolution and intensity can be switched using the reduction ring.

2. Data Storage Unit – OTT NetDL500 / netDL1000

The OTT netDL500 / netDL1000 Data Logger is specially developed for use in hydrometeorological stations. In addition to the task of data collection, these devices can perform all remote data transmission methods. As a result, these data loggers not only meet current usage requirements but are also designed to address future needs.

Based on a modular design, the data storage unit can be configured individually according to the technical specifications of the user, making it a perfect choice for installation in specialized applications.

A powerful GSM/GPRS/3G modem is pre-installed for data transmission to the center (optional). The RS-232 and USB ports, as well as the integrated web server (net DL1000), will support various communication capabilities.

Therefore, users who want higher-level data formats can simultaneously use different communication channels. Short data reading cycles can be set, allowing the data storage unit to operate in a multitasking environment and connect with sensors functioning in parallel.

With large storage capacity and efficient power management, all features of the device can operate easily at the same time and be controlled remotely via a standard browser.
