Build a smarter IoT sensor monitoring solution with our integration-ready IoT Data Logger. The Hawk is Digital Matter’s robust, plug-and-play IoT data logger and sensor hub designed for cellular LTE-M and NB-IoT networks, enabling long-term, low-power deployments in remote and demanding environments.
Purpose-built as a flexible data acquisition system, the Hawk supports a wide range of sensor integrations, making it easy to capture, transmit, and manage critical data across industrial, environmental, agricultural, and utility applications. With secure connectivity, configurable inputs and outputs, and ultra-low power consumption, the Hawk delivers dependable performance wherever data matters most.
Manage tank levels and quality through wireless IoT sensor monitoring to gain real-time visibility into fluid levels, temperature, and pressure. Accurate monitoring helps prevent overfilling or underfilling, reducing the risk of spills, environmental incidents, and equipment damage across fuel, water, chemical, and agricultural storage applications.
Collect weather information using an IoT data logger to build smarter, more efficient weather stations. Capture real-time data on temperature, humidity, rainfall, wind speed and direction, atmospheric pressure, cloud cover, and more, enabling informed decision-making for agriculture, infrastructure, research, and environmental monitoring.
Improve water management and metering through reliable IoT sensor monitoring. Monitor usage patterns, detect leaks, and ensure adequate water supplies are available during periods of peak demand, drought, or emergency response, supporting smarter resource planning and sustainability initiatives.
Efficiently monitor and manage geographically dispersed pumps using the Hawk IoT data logger. Gain visibility into pump status, performance, and run hours, enabling predictive maintenance, reduced downtime, and centralized oversight of remote pumping infrastructure.
Monitor soil moisture and quality to optimize irrigation schedules, reduce water waste, and improve crop yield. IoT sensor monitoring provides actionable insights into soil conditions, helping growers make informed decisions about when to irrigate, when to conserve water, and how to improve long-term soil health.
Deploy IoT sensor monitoring devices for pulse counting applications to accurately measure and log events such as water flow, energy usage, or equipment cycles. This enables precise tracking of consumption, throughput, and operational activity across utilities, agriculture, and industrial environments.

An IoT data logger records data from connected measurement sensors over a defined monitoring period, providing remote visibility into environmental and operational conditions. It functions as a modern data recorder, automatically capturing and transmitting readings without manual intervention.
Devices include internal memory that securely holds stored data when connectivity is temporarily unavailable. Once a connection is restored, the collected data is transmitted automatically to the configured endpoint.
No. Data loggers vary widely depending on sensor support, power requirements, connectivity, and firmware capabilities. Digital Matter’s Hawk is designed for flexibility across industries and integrates easily with modern operating systems and cloud platforms.
Yes. When paired with temperature sensors, IoT data loggers are ideal for cold chain monitoring, helping ensure products remain within required temperature thresholds during storage and transport.
The Hawk is battery-backed, ensuring uninterrupted operation and continuous ability to log data even during power loss or remote deployments where external power is unreliable.
