Monitoring and Controlling of Soil Relative Humidity using Labview

Abstract

The content here gives about the technique which is incorporated to monitor the moisture content in the soil and it enables agriculturalists feasibility of humidity measurement. According to this moisture control sensor circuit, it can observe the corresponding relative humidity and water the plants automatically by observing the conditions using LabVIEW system and myDAQ. The sensed signal from the sensor is interfaced to a LabVIEW loaded PC which acquires the signal as a voltage. With the help of counter pin, a submersible pump turns ON and OFF automatically to water the plants based on soils condition. Farmer can vary the time limit. When the time limit exceeds, he can view the LEDs and buzzer is in ON state. It is applicable in agriculture lands, land irrigation, simple sensors for gardeners.
