Greenhouse Temperature Monitoring Protects Sensitive Flower Species

CLEVELAND - Jan. 23, 2020 - PRLog -- Fresh Cut Flower Farm Uses Automated Greenhouse Monitoring

CAS DataLoggers provided the greenhouse temperature monitoring solution for a large greenhouse currently cultivating several species of popular flowers, an extremely temperature and humidity sensitive process. The temperature and humidity requirements varied from flower to flower, with ideal temperature limits usually being between 57°F and 82°F (14°C to 28°C) with a humidity of 70%-100%.


The greenhouse installed four T&D TR-72wb temperature and humidity data loggers in major areas not covered by the existing climate control system. Each T&D data logger monitored temperatures across a -0°F to 131°F (0oC to +55oC) range with an internal temperature sensor as well as recorded humidity using the external sensor's range of 0 to 95% RH. The T&D logger's  0.5ºC resolution provided highly accurate readings which were clearly displayed on each logger's large LCD display, featuring multi-function viewing to show climate data in real-time. Each logger's memory stored up to 16,000 samples (at 8,000 per sensor) with a user-set sampling frequency from every second to every hour. Customized alarm settings notified growers whenever temperatures suddenly went out of specification.


Personnel were able to quickly install the TR-72wb's and connect them to the WiFi in the greenhouse. The dataloggers monitored the microclimate in tandem with the climate control system, covering the 'blind spots' in its fixed sensors. Functioning like portable weather stations for monitoring the greenhouse in detail, the humidity loggers gave key information on the microclimate, such as temperature drops or changes in the diurnal range, by linking the temperature to the humidity info. This combination of historic and current data was invaluable when growers collected comprehensive meteorological information to reduce risk to the crop by taking measures to limit the negative effects of uncontrollable environmental conditions. This allowed them to achieve optimum plant growth while minimizing disease risk.


The greenhouse benefited in several short- and long-term ways from installing the T&D  temperature and humidity data loggers. Most importantly, the TR-72wb's provided constant temperature and humidity monitoring at high accuracy with customizable alarm settings. The T&D Temperature and Humidity Loggers made for an economic greenhouse fixture, as they were easily installed and retrieved by staff so that growers were able to get a comprehensive temperature and humidity profile of the environment and adjust conditions to obtain maximum healthy plant growth.
