Eco-friendly strategy for CO enrichment performance in commercial greenhouses based on the CO spatial distribution and photosynthesis.

CO enrichment is an essential environmental control technology due to its significantly enhancing effect on crop production capacity. Despite being a key energy consumer in protected agriculture (i.e.

Yield Visualization Based on Farm Work Information Measured by Smart Devices.

This paper proposes a new approach to visualizing spatial variation of plant status in a tomato greenhouse based on farm work information operated by laborers. Farm work information consists of a farm laborer's position and action. A farm laborer's position is estimated based on radio wave strength measured by using a smartphone carried by the farm laborer and Bluetooth beacons placed in the greenhouse.
