⚡ 100A YHDC Non-Invasive AC Current Sensor
Clamp-Type • Safe Measurement • Energy Monitoring
📌 What is this sensor?
The 100A YHDC Non-Invasive AC Current Sensor (commonly SCT-013-000) is a current transformer (CT sensor) used to measure alternating current (AC) without direct electrical contact.
👉 It is called non-invasive because:
  • You don’t need to cut wires
  • Just clip it around a conductor
✔ Widely used in energy monitoring and IoT systems
⚙️ Working Principle
  • Works on current transformer principle
  • The wire acts as primary winding
  • Sensor coil acts as secondary winding
Process:
  • AC current flows through wire
  • Magnetic field is generated
  • Sensor coil detects this field
  • Produces proportional output current/voltage
✔ No direct electrical connection → safe measurement
🔌 Output Types
Two common versions:
1. Current Output (e.g., SCT-013-000)
  • Output: small AC current (e.g., 50mA)
  • Requires burden resistor to convert to voltage
2. Voltage Output
  • Built-in resistor
  • Direct voltage output (easy to use)
🔌 Physical Features
  • Split-core clamp design
  • 3.5mm audio jack output
  • Cable length ~1 meter
  • Clip-on installation
✔ Can be attached without disconnecting wires
📊 Technical Specifications
  • Rated Current: 0 – 100A AC
  • Max Current: up to 120A
  • Output: 50mA (typical)
  • Turns Ratio: ~1:2000
  • Accuracy: ±1%
  • Frequency Range: 50Hz – 1kHz
  • Operating Temp: -25°C to +70°C
  • Max Voltage: up to 660V
  • Core Material: Ferrite
  • Opening Size: ~13mm
🔄 Output Behavior
  • Output is AC waveform proportional to current
  • Must be:
    • Converted to voltage
    • Sampled using ADC
✔ Not a direct digital sensor
✨ Key Features
  • Non-invasive (safe and easy installation)
  • High accuracy (~±1%)
  • Wide current measurement range
  • Compact and durable
  • Supports both current & voltage outputs
  • Flame-retardant casing (UL94-V0)
🛠️ Applications
  • Home energy monitoring systems
  • Smart meters
  • IoT power monitoring
  • AC motor monitoring
  • Load detection systems
  • Industrial current measurement
⚡ Advantages
  • No direct electrical contact
  • Safe for high-voltage systems
  • Easy installation (clip-on)
  • Long lifespan
  • Ideal for DIY and IoT projects
⚠️ Limitations
  • Works only with AC (not DC)
  • Requires signal conditioning circuit
  • Accuracy reduces at very low current
  • Needs calibration for precise readings
💡 Important Notes
  • Clamp only one wire (live OR neutral, not both)
  • For Arduino:
    • Use burden resistor + biasing circuit
  • Output is small → requires amplification/filtering
  • Choose correct current rating for better accuracy
