Data collection and monitoring of the environment, water conditions, and media are essential for commercial growers trying to push their plants to their full genetic potential. With a small array of industry-focused sensors or handheld devices, forward-thinking cultivators gain access to valuable insights into the long list of factors directly impacting their garden’s overall growth and health.

With real-time and historical information, data from sensors can be used to create log books with detailed notes that paint a clear picture of where things may be going wrong throughout production cycles. Ultimately, the key indicators provided by sensors help growers create standard operating procedures that lead to consistent, high-yielding crops.

What are the different types of sensors?

There are several different types of sensors used to monitor and control various aspects of the cultivation facility, including water, nutrients, and environmental conditions. Sensors use many different communication protocols and proprietary technologies to produce real-time data for water parameters, environmental status, and media conditions. On the entry-level side, they’re available as simple, standalone handheld devices capable of data logging over short periods. However, larger facilities will want to consider sensors built for automated control systems with customizable user-defined setpoints and long-term data storage options.

Being able to monitor the status of nutrient solutions, run-off from irrigation, and incoming water supplies are essential metrics for commercial cultivators to monitor. Sensor manufacturers have created devices capable of measuring a wide variety of water conditions for both the water supply and the growing media. These sensors can measure parameters like pH, electrical conductivity, temperature, dissolved oxygen, and oxidation-reduction potential. Some of these monitoring solutions are available as handheld devices that may include two or three sensors in one small unit. In most cases, tracking tools for pH, temperature, and electrical conductivity are included in one device.

Knowing the conditions of the growing environment helps cultivators understand how plants are progressing and how water is moving from them into the environment. Companies have created sensors for monitoring temperature, humidity, CO2 levels, and light conditions. Environmental sensors are available as handheld devices, but many work in conjunction with automated control systems run through a local network or cloud-based system with remote monitoring services.

Sensors: a critical tool for cultivators

Data is a grower’s best friend. Understanding how the garden responds to different inputs allows growers to fine-tune devices to maintain their desired growth conditions and push their plants to reach their full genetic potential and retail price point. Using sensors to get real-time data and log historical data is essential for any professional grower looking to maximize their yields while ensuring consistent and replicable results in outdoor, indoor, and greenhouse gardens.
