A data logger is a compact, battery-powered device equipped with an internal microprocessor, data storage, and one or more sensors. It can be deployed in various environments to record measurements at set intervals. The device automatically monitors and records environmental parameters over time, allowing conditions to be measured, documented, analysed, and validated. The data logger contains a sensor to receive the information and a computer chip to store it. The information stored is then transferred to a computer for analysis.

## **Benefits of Using Data Loggers**

Whether it is recording temperature, humidity or anything else, there are many benefits to using a data logger or recorder in Malaysia:

- **Automated Data Collection:** Reduces the need for manual data collection, saving time and resources.
- **High Accuracy:** Provides precise and reliable measurements for critical applications.
- **Continuous Monitoring:** Records data 24/7, capturing trends and patterns over extended periods.
- **Remote Accessibility:** Allows for remote access to data, enabling real-time monitoring and analysis.
- **Versatile Applications:** Suitable for a wide range of industries and monitoring needs.

## **What Data and Measurements Can a Data Logger Collect?**

Depending on the particular data logger, measurements and parameters can include a wide range, such as: air temperature, humidity, AC/DC current and voltage, differential pressure, time-of-use (lights, motors, etc.), light intensity, water temperature, water level, dissolved oxygen, soil moisture, rainfall, wind speed and direction, leaf wetness, pulse signals, room occupancy, plug load, and many more. The type of sensor integrated or connected to the data logger determines the specific parameters that can be measured.

## **Types of Data Loggers**

Data loggers come in various types, each designed for specific measurement needs:

- **Temperature Data Loggers:** Monitor and record temperature changes over time, crucial for applications like food storage, pharmaceuticals, and environmental monitoring.
- **Humidity Data Loggers:** Measure and record humidity levels, essential in environments where moisture control is critical, such as museums, warehouses, and greenhouses.
- **Pressure Data Loggers:** Monitor pressure changes in systems like pipelines, HVAC, and weather monitoring, helping identify leaks and optimise performance.
- **Voltage Data Loggers:** Record voltage fluctuations in circuits and equipment, aiding in troubleshooting, power quality analysis, and electrical safety.
- **Current Data Loggers:** Record AC or DC current flow, use to detect overload condition, diagnose faulty electrical equipment or for load profiling.
- **Light Data Loggers:** Measure and record light intensity, valuable in agriculture, horticulture, and environmental research for studying light patterns and plant growth.
- **Shock Data Loggers:** Capture impacts and vibrations, ideal for monitoring sensitive equipment during transport, preventing damage, and ensuring safe handling.
- **Water Data Loggers:** Track water parameters like level, temperature, and dissolved oxygen, crucial for environmental monitoring, water management, and aquaculture.
- **GPS Data Loggers:** Record location data for asset tracking, fleet management, and wildlife monitoring, providing valuable insights into movement and location.
- **Acceleration Data Loggers:** Measure and record acceleration forces, useful for structural monitoring, vehicle performance analysis, and other applications.
- **Multi-parameter Data Loggers:** Measure two or more parameters like temperature, humidity and pressure at the same time.

## **How Do Data Loggers Work?**

Data loggers, sometimes referred to as data recorders, capture and store data using a simple yet powerful process:

- **Sensing:** The data logger's sensor(s) detects and measures the environmental parameters of interest, such as temperature, humidity, or pressure.
- **Processing:** The built-in microprocessor converts the sensor's readings into digital data.
- **Storing:** This digital data is stored in the logger's internal memory at specified intervals.
- **Transferring:** The stored data can be later transferred to a computer or other device for analysis and visualisation, often using USB or wireless communication.

This process allows data loggers to autonomously monitor and record environmental conditions over time, providing valuable insights for various applications.

## **What Are the Key Features of a Data Logger?**
- The devices are usually compact and portable for use in the field and the laboratory.
- Data can be measured automatically using computer control, meaning there is no need for a physical presence, saving valuable resources.
- Some data loggers have a handy USB plug-in interface or a wireless Bluetooth feature that makes data transfer easier and more convenient.
- The data loggers can be accessed remotely, and readings can be stored for later analysis in the laboratory or office.
- Some data loggers have an IP rating to withstand environmental elements while collecting data.
- Data can be collected 24 hours a day, 365 days a year.

## **What Factors Should I Consider When Choosing a Data Logger?**

Selecting the right data logger depends on your specific needs and the nature of your application. Here are some key factors to consider:

- **Measurement Parameters:** Determine the specific environmental parameters you need to monitor, such as temperature, humidity, pressure, voltage, or other variables. Choose a data logger with the appropriate sensors for your needs.
- **Accuracy and Resolution:** Consider the required accuracy and resolution for your measurements. Higher accuracy and resolution provide more precise data, crucial for scientific research or critical applications.
- **Measurement Range:** Select a data logger with a measurement range that covers the expected values in your environment. Ensure the logger can handle both the minimum and maximum values you anticipate.
- **Number of Channels:** Determine how many sensors you need to connect to the data logger simultaneously. Choose one with the appropriate number of channels to accommodate your sensors.
- **Sampling Rate:** The sampling rate determines how often the data logger records measurements. Choose a sampling rate that captures the necessary data frequency for your application.
- **Data Storage Capacity:** Consider the amount of data the logger needs to store. Choose a data logger with sufficient memory capacity for monitoring duration and sampling rate.
- **Power Source:** Data loggers can be powered by batteries, external power sources, or even solar panels. Choose a power source that suits your application and provides reliable operation.
- **Environmental Durability:** If the data logger will be exposed to harsh conditions, such as moisture, extreme temperatures, or dust, select a model with appropriate environmental protection ratings (e.g., IP67 for water resistance).
- **Connectivity:** Consider how you will access and retrieve the recorded data. Data loggers offer various connectivity options, including Wi-Fi, Bluetooth, USB, and cloud connectivity. Choose a connectivity option that aligns with your data access and analysis needs.
- **Compatibility with Sensors and Probes:** Ensure the data logger is compatible with the sensors and probes you plan to use. Check for compatibility with sensor types, connector types, and communication protocols.
- **Software and Data Analysis Features:** Evaluate the software provided with the data logger for data analysis and visualisation. Some data loggers offer advanced software features for data manipulation, graphing, and reporting.
- **Portability and Size:** Consider the size and portability of the data logger, especially if you need to deploy it in the field or carry it around. Choose a compact and lightweight model if portability is essential.
- **Calibration Requirements:** Determine whether the data logger requires periodic calibration to maintain accuracy. Check the recommended calibration intervals and procedures.
- **Battery Type and Life:** Consider the type of battery used by the data logger and its expected lifespan. Some data loggers use replaceable batteries, while others have rechargeable batteries.
