The design and development of the weighbridge using STM32 Microcontroller for measuring the weight of the vehicle using Load cell and STM32 Microcontroller offers a reliable and efficient solution for the weight measurement. Weighbridge plays a crucial role in the industry. In this project, an STM32 microcontroller is used to control the load cell and convert the analog weight measurement data into digital form. The weight measurement data is transmitted to a cloud server using an ESP8266 microcontroller.

The STM32 orchestrates the entire weighbridge system, leveraging its high-resolution analog-to-digital converters (ADCs) and precise timers to ensure the utmost accuracy in weight measurement. The load cell is used to measure the weight of the vehicle. The data from transfer the load cell to STM32 microcontroller using RS232 Serial Communication. The ESP8266 microcontroller is used to transmit the weight measurement data to the cloud.

The use of the STM32 microcontroller and load cell ensures accurate weight measurement, while the ESP8266 microcontroller and Blynk cloud platform provide a convenient way to store and analyze the data. Blynk allows users to log and visualize historical data from their IoT devices, making it easier to track trends and analyze data over time. Blynk serves as the central repository for weight data, offering cloud-based storage, advanced data analytics, and real-time accessibility, revolutionizing how weighbridge data is managed and utilized.
