Revolutionizing Indoor Farming With IOT Agriculture Sensors

IOT agriculture sensors

The way agriculture happens is changing. In fact, it's gaining ground in a familiar environment: the great indoors.

In recent years, indoor farming has taken off and is becoming increasingly popular due to its ability to produce high-quality crops while using limited amounts of space, resources, and energy.

The shift to indoor agriculture operations – though not new – is becoming a necessity as traditional agriculture is facing challenges to its sustainability and ability to meet demand.

For those managing an indoor agriculture operation of any sort, there's nothing more important than maintaining as much control as possible over the environment. Just like growing fruits and vegetables outdoors (or raising livestock), even one small change in growing conditions can have a major impact on a successful harvest.

That's where IoT agriculture sensors come in.

When carefully integrated into the systems and environments of indoor agricultural operations, IoT sensor technology gives next-gen farmers the upper hand in optimizing growing conditions for maximum crop production and yield.

For the purpose of this article, we'll zero in on indoor vegetable growing. Keep in mind: many of the same benefits advanced sensor technology brings to managing controlled environment vegetable farming can be applied to indoor livestock operations as well.

The Ongoing Evolution of Agriculture

The state of agriculture is in an interesting and transitional time. 

Traditional farming isn't what it used to be.


  1. In 2023,  there were only 1.89 million farms in the U.S. – less than a third of a 6.8 million-farm peak almost a century earlier.

  2. In the last five years,  the number of farms in the U.S. decreased by 141,733, and the decline is poised to continue through the coming decades. The same is expected globally for the rest of the century.

  3. Farmable land is decreasing year over year, and that's not expected to change any time soon.

Yet the need for produce and livestock products has not gone away, nor will it. The simple fact is that people need to eat, and almost all the food that stocks grocery store shelves can trace its roots back to a farm.

What's more, eating habits are changing, with more people worldwide choosing plant-based diets.

So how do you feed a hungry planet against the challenges faced by traditional agriculture? 

The answer is essentially bringing the farm indoors.

Controlled environment farming operations, which encompasses indoor growing practices such as hydroponic and vertical farming, are becoming more common. And, pardon the pun, it's an industry that's only  expected to grow.

The success of controlled environment farming largely depends on one major thing: controlling the indoor environment so it's conducive to growing plants.

And it's not just advanced sensors that help climate control systems keep indoor environment metrics within appropriate ranges. Now, it's IoT- (Internet of Things) enabled advanced sensors integrated into HVAC, lighting, and irrigation systems that make this latest iteration of agriculture possible.

What Are IoT Sensors & How Do They Work?

IoT sensors in indoor agriculture are sophisticated devices designed to capture and relay data on environmental conditions and transmit it to a central processing system. This system analyzes the data to provide actionable insights and engage various indoor climate control systems to optimize conditions for crop development and health.


The IoT Agriculture Sensors That Make Indoor Farming Fruitful

Although indoor growing operations are each unique, the IoT agriculture sensors enabling controlled environment farming are consistent across all enclosed agricultural spaces.

Keeping indoor environmental conditions within an ideal range means monitoring and controlling a combination of factors that, in a grand sense, mimic the dynamics of the natural environment. While it's impossible to duplicate things like the sun, wind, and weather patterns, IoT sensors integrated into the systems controlling an indoor environment make it possible to get pretty close. With their data helping to automate and engage climate control systems, controlled environment farms can meet the needs of what's being grown on demand.

Whether you're designing or upgrading any one of an indoor farm's climate control systems, the IoT agriculture sensors that are a must for any operation include:

  • Humidity Sensors for keeping ambient airborne moisture levels in check, thereby promoting plant disease prevention and optimal growth conditions.

  • Temperature Sensors to ensure the indoor farming environment remains within the optimal temperature range for plant growth.

  • Indoor Air Quality Sensors to monitor the concentration of airborne pollutants, including CO2, and the overall air quality within the indoor farming setup. At the same time, keeping CO2 levels within a precise range is critical to photosynthesis and, in turn, a healthy crop.

  • Light Sensors for monitoring natural and artificial light levels in indoor farming settings.

  • Soil pH Sensors to measure the acidity or alkalinity of the soil, a crucial factor in nutrient availability to plants.

  • Leaf Color Sensors to assess plant health. Changes in leaf color can indicate nutrient deficiencies, water stress, or disease.

IoT Sensors for Precision Agriculture & a Bountiful Harvest

There's no such thing as too much data.

This is especially true – and practically a necessity – for indoor agriculture.

The more actionable data farmers have on the growing environment and crops from things like smart greenhouse sensors, the more they can fine-tune climate control and growing systems with pinpoint accuracy for: 

  • Creating Optimal Growing Conditions: Constant monitoring and adjustments made possible by IoT sensors maintain ideal conditions for plant development, directly contributing to higher yields and superior quality crops. An example: Data collected by temperature and moisture sensors in agriculture can be used to create better irrigation schedules that provide plants with the right amount of water.

  • Enhancing Crop Monitoring and Management: Real-time data from IoT sensors help paint an accurate picture of crop health and environmental conditions, enabling immediate adjustments to improve plant growth and prevent issues from escalating. For instance, a spike in humidity levels can be quickly mitigated by the indoor farm's HVAC system to prevent plant diseases.

  • Reducing Energy, Water Use, and Waste: With the help of IoT sensors, indoor farming operations have better control over resource use. This not only helps reduce costs but also minimizes environmental impact by conserving energy and water resources and reducing waste.

  • Increasing Productivity With Decreased Labor: Creating wireless sensor networks in agriculture through IoT technology all-but-eliminate the need for manual monitoring and data collection, freeing up farmers to focus on other important tasks. This eliminates human error in data collection and enables better decision-making based on accurate information.
