In today’s data-driven world, precise and reliable environmental monitoring is essential across various industries. Whether you’re tracking temperature, relative humidity, or light intensity, the DL-4C Data Logger by Onset offers a versatile solution for wireless data collection and transmission. With Bluetooth Low Energy (BLE) technology and support for additional sensors, the DL-4C is designed to meet the demands of modern monitoring applications. In this post, we’ll explore the key features and capabilities of the DL-4C Data Logger, and how it can elevate your data collection process.
Wireless Monitoring Made Easy
The DL-4C Data Logger is a self-contained, wireless device that allows you to monitor temperature, relative humidity, and light intensity data with ease. Using BLE technology, this data logger can transmit data to your mobile device or Windows computer over a 100-foot range, providing the convenience of accessing your data anytime, anywhere. With the free HOBOconnect app, you can easily view, analyze, and export your data, ensuring you have the information you need at your fingertips.
Flexible Channel Options: 1-Channel vs. 4-Channel
The DL-4C Data Logger comes in two configurations: a default 1-channel option and an upgraded 4-channel version. The 1-channel DL-4C is ideal for measuring temperature, relative humidity, and light intensity, making it perfect for basic environmental monitoring tasks. However, if your application requires monitoring multiple parameters simultaneously, the 4-channel DL-4C offers the flexibility to connect up to four external sensors. This option transforms the DL-4C into a robust, multi-sensor data logger capable of handling more complex monitoring requirements.
For those using monitors with a current analog output signal, the DL-4C is the perfect fit. If you need a data logger for monitors with a voltage analog output signal, the DL-4V variant is available. Depending on your setup, you can choose between one and three additional cables for the DL-4V. While the default option includes a 4-20 mA cable, we offer the ability to customize your order with different cable types to suit your specific needs. Simply contact us to process a custom order.
