Greenhouse Temperature Monitoring Protects Sensitive Flowers
Ohio Pen/10281898

CLEVELAND - OhioPen -- Fresh Cut Flower Farm Uses Automated Greenhouse Monitoring

CAS DataLoggers provided an environmental monitoring solution for a large greenhouse cultivating several species of popular flowers, a highly temperature and humidity-sensitive process. The temperature and humidity requirements varied from flower to flower, with ideal temperature limits typically between 57°F and 82°F (14°C to 28°C) and a humidity of 70%–95%.

Key Factors in Greenhouse Management

Temperature and humidity were measured at the plant canopy to ensure accuracy. These factors heavily influence the greenhouse's microclimate and are crucial for optimal growth and disease prevention.

Challenges of Traditional Monitoring

Initially, inexpensive thermometers were used, but they were time-consuming and inaccurate. A later HVAC system improved climate control but was limited to fixed measurement points.

The Need for a Comprehensive Monitoring Solution

The greenhouse owner and growers required a temperature and humidity monitoring solution that was:

• Powerful yet affordable for all greenhouse operations
• Flexible enough to allow mapping humidity distribution as well as hot and cold spots
• Effective in evaluating ventilation, heating, and irrigation

The greenhouse installed four T&D loggers to monitor temperature and humidity in key areas. Each logger displayed accurate readings on a large LCD screen, stored up to 8,000 data sets, and provided alarms for temperature deviations. Cloud hosting enabled remote data access and Wi-Fi connectivity simplified setup. The loggers monitored microclimate "blind spots," providing detailed information to help growers reduce crop risks and optimize growth conditions.

The data loggers eliminated manual temperature readings. All climate information was stored and accessible via web storage. The data aided in disease prediction, allowing for timely preventative measures. Free configuration software simplified programming and data downloading. Cloud software enabled the combination of readings from multiple loggers into a single display.

Benefits

The greenhouse benefited in several short- and long-term ways from installing the T&D temperature and humidity data loggers. Most importantly, the TR-72A2s provided continuous, high-accuracy temperature and humidity monitoring with customizable alarm settings. The T&D temperature and humidity loggers proved to be a cost-effective greenhouse fixture. They were easily installed and retrieved by staff, enabling growers to obtain a comprehensive temperature and humidity profile of the environment and adjust conditions for maximum healthy plant growth.
