Rancang Bangun Alat Pemberi Makan Entok Otomatis Berbasis Internet of Thing (IoT)

A system using Internet of Things (IoT) technology has been developed to assist farmers in efficiently feeding their pet ducks. This system based on the Internet Of Things (IoT) method, involves various components such as loadcell and ultrasonic sensors, servo motors, a real-time clock, LCD display, power supply, and the NodeMCU ESP8266 microcontroller. The feeding process starts by filling the feed into a container hopper. The ultrasonic sensor detects the feed level and sends this information to the Blynk application. The application then opens servo motor 1 to drop the feed into a small container with a loadcell. The loadcell sensor measures the weight of the feed, and then servo motor 1 closes and servo motor 2 opens until the feed runs out, at which point servo motor 2 closes. The system continuously repeats this process and sends notifications to the Blynk application when the hopper is empty. Overall, this system helps to streamline the feeding process for pet ducks and improve efficiency for farmers.

Internet of things with NodeMCU ESP8266 for MPX-5700AP sensor-based LPG pressure monitoring

The use of liquefied petroleum gas (LPG) cylinders as fuel has become a basic need for the community. LPG is more efficient than oil stoves, but LPG also poses a danger. The dangers contained in gas cylinders cause users to be afraid to check the availability of gas in cylinders because the checking process must be directly close to the gas cylinder. Because of this danger, users do not check gas availability, causing it to run out of gas when cooking. To solve this problem, a system is needed to detect the availability of LPG contents, which can be monitored remotely so that users will feel safe because they are not close to gas cylinders. The condition of gas cylinder availability can be remotely monitored using the internet of things (IoT) method. Therefore, an IoT-based LPG pressure monitoring tool was designed.
