The DL-110-E/DL-120-E are Data Logger devices that can be used to record illumination, temperature, humidity and dew point data, together with date and time stamp information. Up to 600,000 downloadable records can be stored. Real-time data can be accessed from the DL-110-E/DL-120-E device from anywhere and at any time using the free Windows software, the iOS App or the Android App, as long as they are connected to the same local network as the Data Logger. The DL-110-E/DL-120-E supports popular industrial protocols such as DCON, Modbus RTU, Modbus TCP, as well as the emerging machine-to-machine (M2M)/IoT (Internet of Things) connectivity protocol – MQTT. The DL-110-E/DL-120-E Data Logger can be connected using a variety of communication interfaces, including Ethernet and RS-485, meaning that the device can be easily integrated into existing HMI or SCADA systems, and are easy to maintain in a distributed control system.

Greenhouse Automation Cloud Management Solution
The greenhouse automation system can use the DL series to provide environmental monitoring such as illuminance (DL-110-E/DL-120-E), temperature and humidity (DL-300/DL-100 series), etc., to make plants grow well, increase crop yield, improve quality, provide product traceability record, and control of sunshine and sprinkler systems. Install WISE-523xM-4GE IIoT smart host with iCAM series network camera can carry out greenhouse monitoring and management, provide further personnel access and thief intrusion monitoring. When finds someone intrusion, it will automatically send SMS, LINE/WeChat to the owner, security and related personnel, to quickly protect property and safety. WISE supports cloud management software IoTstar, so owners can easily build cloud management system solutions and keep with the latest situation in the greenhouse.

 Support the MQTT protocol for IoT Applications
The MQTT protocol is designed for the effi cient exchange of realtime data between a sensor and a mobile device. It operates via TCP/IP and is in widest use today in “machine-to-machine” (M2M) and “Internet of Things” applications.

Built-in Web Server
The built-in web server provides the ability to easily log in to the DL-110-E/DL-120-E module via a standard web browser, allowing users to monitor the data and confi gure the settings without the need to install any software on the terminal.

● Free and Powerful DL300 Utility
The DL-300 Utility can be used to confi gure a module and monitor real-time data, as well as display the run chart, log alarm events, or group DL-110-E/DL-120-E modules so that the status of distribution groups can be viewed and managed. The utility also allows the log data to be downloaded and exported to a .CSV fi le that can then be imported into any industry-standard software or spreadsheet for analysis.

 Get Real-time Data Anywhere and Anytime

The iAir App is a free and easy to install application for iOS or Android Phones or Tablets, and can be used to obtain real-time data from DL-110-E/DL-120-E modules over a Wi-Fi network anytime and anywhere. The iAir App can access a DL-110-E/DL-120-E module either by specifying a specific IP address or by searching for all modules connected to the same Ethernet segment.
