Welcome to the next tutorial of our raspberry pi programming tutorial. The previous tutorial showed us how to set up a weather station using the Internet of Things (IoT) on a Raspberry Pi 4. First, we studied how a weather station works on a fundamental level. Then we developed a Python script to collect data from the station. In contrast, we'll construct an automatic gate using a Raspberry Pi, a load cell, and an HX711 weight sensor.
