Description

The Metal Detector Sensor Module is built around an oscillator circuit driving a small coil, detecting metal within 1cm to 6cm range using electromagnetic induction, responding within 0.5 seconds at just 15mA current draw, operating from 3.3V to 5V DC. The metal detector sensor’s internal oscillator continuously generates a high-frequency electromagnetic field through the coil; when a piece of conductive metal enters this field, the resulting eddy currents draw energy from the oscillator, detectably reducing its amplitude.

The metal sensor price reflects a sensor designed for fast industrial-style sorting and screening applications — the metal detector sensor arduino’s sub-0.5-second response time makes it suitable for detecting metal objects moving past on a conveyor belt at moderate speeds, distinguishing this from slower presence-detection sensors that prioritize accuracy over speed. This metal sensor detector’s low 15mA current consumption also makes it practical for battery-powered handheld or portable detection tools that need extended operation between charges.

The metal detector module’s 1cm-6cm detection distance is intentionally short for this inductive design, since longer-range metal detection typically requires a larger coil and significantly more power, trading portability and compactness for range. One practical trade-off: industrial sorting lines wanting to detect metal at greater distances or with finer object-size discrimination would need a larger industrial-grade inductive sensor rather than this compact module. StemVolt provide, sensor module is well-suited for makers building conveyor-belt metal screening systems and practical fast-response detection electronics projects.

Frequently Asked Questions
What metals can a Metal Detector Sensor Module detect?
+
The Metal Detector Sensor Module detects all common metals including iron, copper, aluminium, and brass using electromagnetic induction. Ferrous metals trigger the sensor from a greater distance within the 1cm to 6cm detection range than non-ferrous ones.
What is the detection range of this metal detector sensor?
+
The metal detector sensor detects metal objects from 1cm up to 6cm depending on the metal type and size. Larger ferrous objects trigger it from the full 6cm range, while smaller non-ferrous pieces may need to be within 2cm.
How do I connect a Metal Detector Sensor Module to Arduino?
+
Connect VCC to 5V, GND to GND, and the signal pin to any Arduino digital input. The Metal Detector Sensor Module outputs HIGH on detection. Use digitalRead in your sketch to read the state and trigger an action.
Does this metal detector module work with ESP32 or NodeMCU?
+
Yes, the metal detector module runs on 3.3V to 5V DC, so it works with ESP32 and NodeMCU directly. Connect the signal pin to any GPIO and read the digital output using Arduino IDE or MicroPython.
How fast does a Metal Detector Sensor Module respond to metal?
+
The Metal Detector Sensor Module responds in under 0.5 seconds, which covers most slow to moderate-speed conveyor sorting tasks. For high-speed applications above one object per second, test the response against your specific line speed before deploying.
