Bayite DC 5-120V 100A Mini Digital Ammeter with Hall Effect Sensor | Isolated Readout

Compact, versatile power monitor

Bayite's DC 5-120V 100A digital ammeter is a reliable tool for watching power in real time. Built around a Hall Effect sensor, the unit provides electrically isolated readings that protect your sensitive equipment while staying easy to wire through a through-hole design. It supports both directions of current, so you can monitor positive or negative flow without pre selecting a direction. This makes it a flexible choice for a wide range of DIY and professional projects where space and simplicity matter.

Key benefits at a glance

• Through-hole design simplifies wiring and installation in panels, enclosures, or breadboard-like setups.
• Measures positive or negative current with no direction limitation for flexible monitoring.
• Electrical isolation from the high voltage side reduces interference and safety concerns.
• Display modes include voltage (5V–120V) or current (0–100A) for quick checks.
• Large wire compatibility with a 19 mm (3/4 in) sensor hole for robust connections.
• Loop-through sensing lets you reinforce weak signals by increasing passes through the sensor (example below).

• Real-time voltage monitoring helps compare components during setup or testing.
• Current monitoring supports power management in LED projects, charging circuits, or small motor controllers.
• Compact form factor fits tight workstations, control panels, or portable rigs.
• Simple wiring reduces setup time for hobbyists and engineers alike.
• The 19 mm through-hole accommodates larger gauge wiring for sturdy installations.
• Looping capability provides a practical way to improve readability when the signal is faint.

In practice, if your current signal is small, you can loop the conductor through the sensor multiple times to magnify the reading. For instance, looping 10 times could make a 0.2 A signal appear as 2.0 A, improving visibility without changing the circuit.

Display options include showing either voltage or current, enabling quick live checks during setup or troubleshooting. While the meter provides clear, real-time readings, outcomes depend on your wiring, connectors, and load. This Bayite gauge is designed as a practical monitoring tool for hobbyists and professionals who want a compact, isolated, easy-to-integrate solution for power measurement.
