Analog vs Digital Signals: How Sensors and Controllers Work Together!

How do computers understand real-world signals like temperature, pressure, or flow? In this video, we break down the difference between analog and digital signals, how sensors capture data, and how controllers process them. We’ll also explore voltage vs. current signals (4-20mA, 0-20mA), ADC/DAC resolution, and take a closer look at the Siemens 6ES7531-7KF00-0AB0 analog input module. If you work with automation, PLCs, or industrial systems, this is for you! 📌 Topics Covered: ✔️ How analog and digital signals work ✔️ How sensors measure temperature, pressure, and flow ✔️ Voltage vs. Current Signals (Why 4-20mA is better for long distances) ✔️ ADC & DAC resolution explained (How precise are the measurements?) ✔️ Siemens 6ES7531-7KF00-0AB0 overview (What can it read?) 🔥 Subscribe to Masoud the Electrician for more electrical and automation insights! 📢 Have questions?
