As Internet of Things (IoT) field is growing very fast in this modern era, and new technologies are coming day by day which are creating huge impact on our life as well is in industrial area. Industrial Internet of Things (IIoT) is a subcategory of IoT. With the advancement of industry trends warehouses are becoming essential part of industry to maintain their stocks. Every product requires specific Environment ie temperature & humidity to maintain its life span. Currently industries are using manual methods to take readings and maintain their warehouse which are not effective. Human errors and mistakes are always possible in an environment of manual methods. These methods are not suitable for warehouses and lead to huge loss in terms of stock which creates high impact on region’s economy. This paper presents the real time implementation of indoor and outdoor temperature & humidity monitoring. Our proposed system has also capability of indoor smoke monitoring of warehouse. The study focuses on the IIoT project to monitor the warehouse indoor and outdoor conditions in real time plus instant notification alert via SMS and e-mail according to thresholds. The method of analysis is performed on Sparkfun ESP8266 Thing Dev Board, NodeMCU implementation with Cayenne MyDevices Cloud. Cayenne MyDevices is a real time Cloud for IoT devices which uses Message Queuing Telemetry Transport (MQTT) Protocol to receive and send data to and from nodes. At hardware level nodes are using DHT22 (Temperature & Humidity) and MQ-2 (Smoke & Combustible gases) Sensors. Nodes will send the sensor readings to cloud via Wi-Fi network. Nodes are easily movable within the area of warehouse due to Wi-Fi mode of communication. This system will work effectively to maintain warehouse environment easily and in a systematic way. Experimental results proved that proposed system works efficiently in warehouse environment to increase the life span of products.
