Introduction to IoT in environmental monitoring

As the world faces an unprecedented climate crisis, it has become increasingly important to monitor the environment and keep track of the impact humanity is having on the world. One of the most promising technologies that can help achieve this goal is the Internet of Things (IoT). IoT in environmental technology allows us to collect real-time data on various environmental parameters, such as air quality, water quality, and soil moisture, among others, leading to actionable insights.

What is IoT in environmental monitoring?

IoT in environmental monitoring is a network of interconnected devices and wireless IoT sensors that collect and transmit environmental data to a central database or cloud platform. The devices, such as wireless sensors and cameras, are equipped with various environmental monitoring capabilities, such as temperature, humidity, air quality, and water quality. This is of great use to farmers using IoT in agriculture or precision farming.

Benefits of IoT in environmental monitoring

Smart factories are comprised of various necessary components that operate together to establish a smooth and productive manufacturing atmosphere. It is worthwhile to examine each of these components in detail.

Real-time environmental monitoring

Real-time monitoring

One of the most significant benefits of IoT in environmental monitoring is the ability to collect and transmit data in real-time. Traditional environmental monitoring methods, such as manual sampling and laboratory analysis, are time-consuming and expensive. With IoT, data can be collected continuously, providing real-time insights into environmental conditions.


IoT in environmental monitoring is also cost-effective compared to traditional methods. Depending on your chosen hardware, the initial investment in IoT devices and infrastructure may be high, but the cost of maintenance and operation is relatively low. IoT devices require minimal human intervention, reducing labour costs, and increasing efficiency.

Increase accuracy with IoT in environmental monitoring

Increased accuracy

IoT devices offer a high level of accuracy and precision in environmental monitoring. The devices can collect data continuously and provide more comprehensive data sets than traditional methods. This enables more accurate predictions and analysis of environmental trends and changes.

Scalability with environmental monitoring


The scalability of IoT in environmental monitoring allows for expansion as necessary, enabling the monitoring of various environmental factors across multiple locations through the addition of sensors and devices.

Applications of IoT in environmental monitoring

Air quality monitoring systems

IoT devices are able to monitor various air pollutants, such as particulate matter, nitrogen dioxide, and sulphur dioxide. The utilisation of IoT technology for air quality monitoring is crucial, specifically in urban regions where environmental pollution is a significant issue and bad air quality can lead to illness.

Water quality monitoring

IoT devices have the capability to monitor different water quality parameters, including temperature, pH, oxygen levels, and turbidity. The monitoring of water quality using IoT technology is crucial in safeguarding aquatic ecosystems, our drinking water and ensuring water safety.

Soil moisture monitoring

IoT devices have revolutionised the way we monitor and manage our environment. One of the most important applications of IoT in environmental monitoring is soil moisture measurement, which is essential for crop management and irrigation. By using IoT devices to track soil moisture levels, farmers can better manage their crops, reduce water consumption, and improve crop yield.

Energy consumption monitoring

As part of an effort to increase energy efficiency, IoT-enabled energy monitoring systems can be used to track energy use in buildings and businesses. With the help of sensors and other connected devices, these systems can collect data on electricity consumption in real time.

Wildlife monitoring

IoT devices can be used to monitor wildlife behaviour and habitat conditions. This information can be used to develop conservation strategies and protect endangered species.

Waste management

Urban areas and cities face a growing issue with waste management. The Internet of Things (IoT) has the potential to enhance waste management practices, boost efficiency, and minimise environmental impact. IoT-based solutions help us monitor waste levels and waste management processes.

Challenges of IoT in environmental monitoring

One of the most significant challenges of IoT in environmental monitoring is managing the large amounts of data generated by devices. This requires robust data storage and analysis infrastructure/tools.

IoT devices are vulnerable to security breaches, and environmental data is sensitive. For this reason it requires protection from unauthorised access. IoT security is critical for an organisation to be on top of. It is crucial that environmental businesses use an IoT provider who understands the importance of security and delivers a robust connectivity solution.

In remote areas, where environmental monitoring is most sought after, providing a stable power supply may be challenging. Thankfully some IoT devices require very little power and can run for a significant amount of time thanks to technologies and protocols such as LPWAN connectivity.


IoT in environmental monitoring has the potential to significantly impact the way we manage our environment and improve human health. It offers a more efficient and accurate method to monitor environmental conditions and make informed decisions about environmental management. Continued investment and development could enable IoT to play a crucial role in mitigating the effects of climate change and preserving the planet for future generations.
