Communication between edge-device raspberry, IOTA tangle network, and web-dashboard could be made remotely.īy using IOTA, the monitoring and control system is also directly connected and recorded in the cloud database. The standard communication protocol (Machine to Machine) used is MQTT to send all of the data from sensors to the local server (MQTT-streams). The Tech: Susukuda_apps infrastructure is a network sensor system consisting of the ESP32 microcontroller (MCU) built-in/integrated with WiFi module as internet connectivity and raspberry as IoT edge device (MQTT-Streams) programmed in the Linux Operating System on computers, which is used to measure CO2, air temperature, humidity, pressure, and liquid temperature on the production process of dairy farm supply chain. Susukuda Infrastructure (IoT Integrated with IOTA) through Stream MQTT Gateway Set values for -u -P to spsecify the username and the password for an authenticated broker. Mosquitto_pub -h localhost -p 1883 -u -P -t "iot2tangle" -m '' Channel root: "47d504e1a825e142dd899dda81ff787c7cfad3b83977feec3545eaef4315c8a50000000000000000:fd93e57d937910f429cdd211" To read the messages copy the channel root into Listening for topic iot2tangle on To send data to the server you can use cURL, make sure the ip and port are the same as in the config.json file, and that they point to the broker: This starts the server which will forward messages from the devices to the Tangle Change topic, node, mwm, local_pow if needed Set the borker_ip, broker_port to match the location on the broker, (default MQTT port is 1883). Set the username, password if you are connecting to an authenticaded broker. Leave username, password empty ("") if your borker does not require authentication. Set the whitelisted_device_ids to include all the device IDs specified in their respective configuration files. To enable authentication through usernames and passwords, follow the steps in If you don't want to set authentication for users run: Sudo apt install mosquitto sudo apt install mosquitto In case you don't have a MQTT broker running yet, you can run one locally with Mosquitto: Sudo apt install cmake sudo apt install cmake Sudo apt install libssl-dev sudo apt install libssl-dev Sudo apt install pkg-config sudo apt install pkg-config Sudo apt install build-essential sudo apt install build-essential Make sure you also have the build dependencies installed, if not run: Install rust if you don't have it already, find the instructions here We have updated some code to this source code. ![]() If you want more detailed information regarding streams-mqtt-gateway, check the official page. Setting Up Streams MQTT Gateway on Raspberry Pi 3 Provides dairy farms with the ability to monitor, organize and face any imminent risk, by alerting on time and suggesting them corrective action that have to be done to avoid any product spoilage.Help dairy farmers grow their business, by improving the safety of their products.Optimizing precision and better practice.Simplifying the time-consuming process of storage monitoring. ![]() ![]() The brand owner is confident that the product is transported and arrives at the right temperature. To achieve milk storage safety and eliminates milk waste, caused by non-efficient storage, is essential to monitor temperature-controlled rooms in order to ensure specified health and quality. With real-time analytics, it is aimed to simplify the sampling process for quality control, maximize precision and efficiency, and provide the customers with the ability to monitor their products remotely. It could be used for a long time in dairy farms to approach the supply chain. By using the latest technologies, the actual condition of the containers will be automated by adjusting the IoT systems, sensors, and clouds. We have developed IoT and IOTA integration to measure CO2, air temperature, air humidity, liquid temperature, and theair pressure inside the containers of the milk storage, which ensure the freshness and quality of milk for expanding agricultural solutions to the cold chain, especially dairy farm.
