Automatic heat sensing system for nursing seedlings

A student of Nong Lam University built an automatic heat sensing system. This system automatically adjusts the temperature and humidity for the nursery.

Vo Van Chin is assembling the outer aluminum frame of the greenhouse model with automatic heat sensing system.

From now on, household scale gardeners may not have to spend much effort to take care of plants.

A student at HCMC University of Agriculture and Forestry has just created a heat induction system to monitor and automatically adjust the temperature of garden plants, especially ornamental flowers in the nursery.

The system has a simple but highly efficient structure, including a thermal relay, an exhaust fan and a push fan to match the circuit.

Vo Van Chin has designed his automatic heat sensory nursery model with a lightweight aluminum frame with a volume of 1.2m * 0.6m * 0.8m. In order to ensure eligibility for air exchange and photosynthesis plants, all sides of the cage are covered with white nylon paper. Thus, the medium-sized nylon separates the temperature and humidity in the cage from the outside temperature and humidity and does not affect the photosynthesis of the plant.

The operating principle of this system is that when the temperature rises above the limit, the relay will close the circuit. At this time, 2 fans will work to create aeration.

Internal structure of automatic thermal induction model for production of propagation by cuttings and nursery seedlings.

The propeller fan placed underneath has the effect of pushing air into the greenhouse, while the exhaust fan is placed at the top of the opposite side to draw the air out.

This function helps to circulate air inside the cage, creating favorable conditions for plants to perform the gas exchange function and adjust the temperature to the appropriate level.

And the pump will spray mist to increase humidity. Since then, the temperature in the greenhouse will fall.

This automatic heat induction system can control the temperature in the greenhouse and increase the air humidity automatically, impacting well on the productivity of plants by cutting branches and sowing seedlings.

Vo Van Chin tested the incubator with its own automatic heat sensing system for 5 types of plants, including white sails, white leaf trees, pearl chains, five colors of chrysanthemum, and medicinal plants.

The results showed that the above 5 species all grow well in the nursery with automatic heat sensing system.

According to student Vo Van Chin, the incubator has an automatic heat sensing system that makes it easier to import, breed and improve imported varieties.

Since then, it is possible to grow many kinds of exotic plants and flowers in the country with the same quality as growing in foreign countries and lowering prices.
