Soil Humidity Warning System with Humidity Sensor via Line Notification

Abstract

This research aims 1) to create a soil moisture warning system with a moisture sensor via Line Notification and 2) to evaluate the satisfaction of using a soil moisture warning sensor via Line Notification. The sample group is 20 general vegetable farmers using a purposive selection method. The tools used are a soil moisture warning system and a satisfaction assessment form using a microcontroller to process soil moisture, a soil moisture sensor, and a wireless internet system used to notify via Line Notification. This research presents the creation of a soil moisture measurement device that is inexpensive and has an efficiency similar to soil moisture meters that are sold in the market at a relatively high price. From the results of the experiment, the user can measure the amount of moisture in the soil effectively. The data obtained from the measurement is an electrical signal that can be processed and the amount of water used to water the plants can be controlled accurately and appropriately. The results of the evaluation of the efficiency of the soil moisture warning system with a moisture sensor via Line Notification showed that overall, the satisfaction with the system is at the highest level. The average value is at ( = 4.58, S.D. = 0.69).
