Laboratory Automation System Using IOT Devices

This paper describes a Laboratory Automation System using IoT devices. The main hardware modules consist of: ESP8266 micro-controller by Espressif and energy meter HLW8012 by HLW Technology. The communication between the IoT devices uses IEEE 802.11g WiFi network, TCP/IP stack and MQTT protocol. The minimal configuration of the LAS includes one control device called Gateway and one manageable device called Host. The devices can be controlled remotely by user-friendly, simplified web-based interface. The project is published as open source software and hardware.
