เครื่องชั่งน้ำหนักและนับจำนวนอุปกรณ์แสดงผลอัตโนมัติ

Abstract

The Purposes of this research were to design and develop the Equipment number counting weighing machine in store, materials and equipment are constantly shrinking in size, especially nuts and screws, so counting is very necessary. Thus, we have design and develop for to weigh and counting the number of devices in the store helps to count the number of devices. We designed by divided it to 3 parts: Part 1 the load cell converts the pressure into electrical signals HX711 serves to receive the signal from the load cell and convert the value to high precision digital 24Bit signal. Part 2 the ESP32 receives the value from the HX711 signal amplifier to process it. Part 3 display results from weighing and counting equipment. Efficiency of weighing and counting automatic display devices with a maximum error of only 0.2% of weighing and counting devices and accurate alarms show that this research can work efficiently.
