Fabrication of Electronic Device to Maintain Saturated Vapour Pressure in Mist Chamber

Abstract

A simple device to control misting inside the mist chamber has been fabricated. This device consists of a control unit which activates or inactivates the water pump through a sensing device placed inside the mist chamber. This device is highly useful to maintain saturated vapour pressure inside the mist chamber, at the same time prevents both overwatering and underwatering of experimental plants. The cost of fabrication of this device, including control unit is only Rs. 250. The device can also be used for controlled nursery irrigation and lawn irrigation.
