Development of Soil Mixer for Planting by Controlling With IoT System

Abstract

This research aimed to: 1) develop a soil mixing machine controlled by an IoT system and 2) study the results of implementing the IoT-controlled soil mixing machine. The target group consisted of 15 members of the "Fish Waste Processing" Community Enterprise Committee in Lam Khlong Subdistrict, Mueang District, Kalasin Province. The research tool used was a technology acceptance questionnaire. The statistical methods employed included mean and standard deviation.

The findings of the research results were as follows: 1) Development of the IoT-controlled soil mixing machine: 1.1) the IoT control system comprised three main components, 1.2) the technological equipment design included Arduino 8255, Relay Module, and 3G Module, 1.3) the platform used for IoT control was Blynk, a cloud-based platform compatible with both iOS and Android smartphones, 1.4) the soil mixing machine design was inspired by a cement mixer. The design positioned the mixing drum on a cart and mounted the shaft system on the main frame, allowing continuous rotation and mixing. A motor was installed beneath the lever for operation and 1.5) the IoT-controlled soil mixing machine featured the following characteristics: 1.5.1) A mixing drum with a capacity of no less than 5 kilograms, 1.5.2) A motor for the shaft with a power rating of no less than 2 horsepower and 1.5.3) A portable cart-mounted mixing drum for ease of movement. 2) Results of implementation: 2.1) Performance efficiency: The soil mixing machine operated at three adjustable speed levels, reducing the soil mixing time by no less than 20 minutes compared to traditional methods and 2.2) Technology acceptance: Overall, user acceptance of the technology was rated as high. Item-specific ratings ranged from high to very high, with a mean score of 3.98 and a standard deviation of 0.70.
