IoT Based Temperature Control System with Real Time Data Monitoring

Abstract

Internet of Things (IoT) is monitoring of the surrounding parameters and other several tiny devices connected together to the use of sensors that acquaint for wireless sensing of real time data and transfer them into the desired form and help to forward the sensed data across the network cloud via ‘Internet Connection’. The temperature monitoring is becoming more and more important in the daily life. Data monitoring is provided with real time clocks where data is sequentially stored in memory. The proposed system maintains temperature and humidity within defined range of IoT ‘Thingspeak’ web service for the sensors to monitor sensed data at cloud level to the MATLAB using a channel ID and read API key. This paper presents the hardware design use of the NodeMCU, DHT11 humidity sensor and through HTTP that helps to process and transfer the sensed data to the Thingspeak Cloud. A data monitoring shows the record of temperature measurements over a period of time.
