Abstract

Posyandu is a basic health service that plays an important role in integrating the growth and development of infants and toddlers. However, the manual data recording process is still widely carried out, which is prone to errors and delays in recording. This study aims to design and build a baby weight and height measuring system based on ESP32 with integrated sensors and RFID cards, which can automate data recording to Google Spreadsheet in real-time. This system uses a load cell sensor for weight measurement and an ultrasonic sensor for height, as well as an RFID RC522 module for identifying the baby's identity via an RFID card. The measurement data is displayed on a 16x2 I2C LCD screen and is automatically sent to a spreadsheet after the RFID card is attached. The system development method used is Rapid Application Development (RAD), with stages of needs planning, system design, development, and implementation. The test results show that the system can measure and record data with good accuracy and make it easier for Posyandu officers in the data collection process. This system is expected to be a practical and efficient solution in supporting the digitalization of basic health services at the community level.
