A WSN (Wireless Sensor Network) Approach for Controlling the Actuator Wirelessly through Database Interaction

This research study explores the wireless sensor networking, where sensor data is transmitted to a local database via a nearby server. The primary focus of this research study is real-time environment monitoring systems and wireless control and actuation systems. This research study incorporates the DHT 11 (Temperature and Humidity) and MQ-6 (LPG Gas) sensors. Selecting an appropriate controller is crucial to attaining desired system attributes like high-speed precision and meeting requirements for precise motion control at high speeds. That is why the ESP-8266-based NodeMCU is adopted for this research.Furthermore, both feedback and feedforward closed-loop control mechanisms are implemented. As a result, the system can either control the actuator itself or by user demand. Leveraging sensor-derived data, the controller can automatically trigger the actuation system precisely within estimated time. Further, this study also depicts a clear differentiation between conventional methods and the proposed novel approach. Moreover, an IP (Internet Protocol) based monitoring system allows to monitor the sensor-derived data instantly, even without internet connectivity. Notably, the entire system operates on solar power, ensuring uninterrupted functionality even during power outages.
