Although indoor agriculture is not a new concept, it has become increasingly crucial as traditional agriculture faces challenges related to meeting demand and ensuring sustainability. Managing indoor agriculture operations requires meticulous control over environmental conditions, as even minor changes can significantly affect the success of a harvest.

Internet of Things (IoT) agriculture sensors play a critical role in maintaining these controlled environments. By integrating IoT sensor technology into indoor agricultural systems, next-generation farmers can optimize growing conditions for maximum crop production and yield.

While this article focuses on indoor vegetable growing, the advantages of advanced sensor technology in managing controlled environments also extend to indoor livestock operations, providing similar benefits in terms of efficiency and productivity.

The Ongoing Evolution of Agriculture

Agriculture is undergoing a significant transformation, with traditional farming evolving rapidly. As of 2023, the United States had 1.89 million farms, a sharp decline from the peak of 6.8 million farms nearly a century ago.

Over the past five years alone, the number of farms has decreased by 141,733, and this trend is expected to continue through the coming decades. A similar decline is anticipated globally for the remainder of the century.

Farmable land is shrinking annually, and this reduction is projected to persist. Meanwhile, the demand for produce and livestock products continues to grow. Most of the food available in grocery stores originates from farms, and changing dietary preferences, including a shift towards plant-based diets, add to the demand.

Indoor farming presents a promising solution to address the challenge of feeding a growing population amidst the constraints of traditional agriculture. By bringing agriculture indoors, it is possible to meet the increasing demand for food while overcoming many of the limitations faced by conventional farming methods.

Controlled environment farming operations are becoming increasingly prevalent. This industry, which includes indoor growing practices such as hydroponic and vertical farming, is expected to see substantial growth in the coming years.

The success of controlled environment farming is primarily dependent on the farmers’ capacity to maintain an indoor environment that is conducive to growing plants.

Advanced sensors support climate control systems in keeping indoor environment metrics within appropriate ranges, and increasingly, IoT-enabled advanced sensors integrated into lighting, HVAC, and irrigation systems enable this latest iteration of agriculture.

Understanding IoT Sensors and Their Operation

The IoT sensors used in indoor agriculture are sophisticated devices that capture and transmit environmental data to a central processing system. This system analyzes the data to generate actionable insights and automatically adjusts indoor climate control systems, optimizing conditions for crop health and development.

Common IoT Agriculture Sensors

While every indoor growing operation is unique, IoT agriculture sensors used in controlled environment farming share common features across different setups. Monitoring and controlling various factors are crucial to maintaining indoor conditions within an ideal range, often by mimicking natural environmental dynamics.

Although perfectly replicating the sun, wind, and weather patterns is technologically challenging, IoT sensors can closely simulate many of these natural phenomena. By integrating these sensors into climate control systems, controlled environment farms can effectively meet the needs of their crops on demand, using sensor data to automate and adjust environmental conditions.

Whether designing or upgrading an indoor farm's climate control system, several common IoT agriculture sensors are essential for optimizing operation.

  • Humidity sensors help maintain ideal ambient airborne moisture levels, preventing plant diseases and promoting optimal growth conditions.
  • Temperature sensors help ensure that the indoor farming environment remains within the optimal temperature range for plant growth.
  • Indoor air quality sensors help monitor the concentration of airborne pollutants like CO2, as well as overall air quality within the indoor farming setup. Keeping CO2 levels within a precise range is also key to ensuring photosynthesis and, in turn, a healthy crop.
  • Light sensors help to keep track of natural and artificial light levels in indoor farming settings.
  • Soil pH sensors help to measure soil’s acidity or alkalinity. This is a critical factor in ensuring nutrient availability to plants.
  • Leaf color sensors are used to assess plant health because changes in leaf color potentially signal water stress, nutrient deficiencies, or disease.

Using IoT Sensors for Precision Agriculture

There is no such thing as too much data, and this principle is particularly true for indoor agriculture.

The more actionable data farmers can obtain from smart greenhouse sensors about the growing environment and crops, the more precisely they can fine-tune climate control and growing systems. This approach to precision agriculture provides several benefits.

Ensuring Optimal Growing Conditions

IoT sensors enable constant monitoring and adjustments, allowing farmers to maintain the ideal conditions for plant development and directly contributing to higher crop yields and superior quality.

For example, agricultural data collected via temperature and moisture sensors can be leveraged to develop improved irrigation schedules, ensuring plants are consistently provided with the right amount of water.

Enhancing Crop Monitoring and Management

Real-time data from IoT sensors provides farmers with an accurate overview of crop health and environmental conditions. This allows them to make immediate adjustments to improve plant growth while simultaneously preventing potential issues from escalating.

For example, it is possible to rapidly mitigate an undesired spike in humidity levels using the indoor farm's HVAC system, essentially helping to prevent plant diseases.

Reducing Energy, Water Use, and Waste

Thanks to IoT sensors, indoor farming operations have improved control over resource use. This helps lower costs and minimizes the farm’s environmental impact by conserving water and energy resources while reducing waste.

Increasing Productivity with Decreased Labor

The widespread implementation of wireless sensor networks in agriculture via IoT technology has all but eliminated manual monitoring and data collection requirements, freeing up farm workers to focus on other important tasks.

This approach has the added benefits of eliminating the risk of human error in data collection and enabling more reliable decision-making based on accurate information.

Implementing IoT Agricultural Sensors in Indoor Growing Operations

The use of advanced sensor technology in climate control systems is not new. Most designers and manufacturers already use sensor technology to ensure their systems run at peak performance.

However, this is especially important in indoor agriculture because the sensors in agriculture and environmental monitoring require a much higher level of precision and immediate reactivity than in many other applications.

The best option for adding IoT agriculture sensors to indoor farming climate control systems is to partner with an advanced sensor manufacturer. By working with the manufacturer directly, indoor farms are able to take advantage of a range of benefits.

Customization

Manufacturers are able to offer tailor-made solutions suited to the distinct requirements of a specific indoor farming operation. Unlike their off-the-shelf counterparts, custom sensors can be designed to measure specific parameters relevant to plant growth and health, ensuring accurate and efficient monitoring and control.

Integration

An advanced sensor manufacturer will have sufficient expertise to ensure that its products are seamlessly integrated into existing indoor farming systems. It can also offer guidance on incorporating sensors into other climate control system components for cohesive operation, such as HVAC units or irrigation systems.

Innovation

Collaborating with manufacturers directly allows indoor farming operations to access the most up-to-date sensor technologies and innovations. Manufacturers typically invest significant time and resources into research and development, meaning that their clients can benefit from cutting-edge solutions that boast improved reliability, accuracy, and functionality.

Support

Establishing a direct relationship with a sensor manufacturer provides ongoing support and expert advice for indoor farms. This relationship is invaluable for troubleshooting issues, updating technology, and scaling the sensor network to meet the evolving needs of indoor farming operations.

Cost-Effectiveness

Although custom sensor solutions may appear to be more expensive in terms of upfront costs, they are typically highly cost-effective in the long term because they help optimize resource use, reduce waste, and improve crop yields.

A Look Ahead at Farming 2.0

It is difficult to predict exactly what the future of agriculture will look like, but one thing is clear: farming is evolving. Indoor agriculture is not just a fleeting trend; it is a sustainable method that is set for significant growth and broader adoption.
