Technologies Used by a Detector PCB

How Does a Metal Detector PCB Board Function Using a Single Transistor?

A Metal Detector PCB with a single transistor effectively detects metal’s presence from a certain distance. It even detects some of the most sensitive metals.

This PCB operates like an oscillator by using positive feedback. When the base is fixed, the transistor identifies a higher voltage between the base and emitter terminals. Then, the transistor voltage becomes lower compared to the average rating.

There is a capacitor found in between the emitter and the collector. This capacitor affects the emitter potential that switches off and on the transistor. But it switches off when the voltage is promoted to a particular range.

A coil generates an electromagnetic field by cheating a reverse voltage. When a metal enters the electromagnetic field, a frequency variation happens. After this, the PCB imparts low-frequency signals from the loudspeaker.

Here, the transistor deals with a non-saturated amplitude. This frequency change is very low. But, metal detector PCB efficiently detects this variation. The sensitivity of a detector circuit board entirely depends on this factor.

The PCB to receive the frequency change signal when the slightest presence of metal occurs. If you bring the metal close to the circuit, the amplitude gets decreased.

Highly Functional Metal Detector PCB

What Is the Working Principle of a Smoke Detector PCB?

A Smoke Detector PCB is a circuit board that reliably recognizes smoke in different settings. For instance, it is used in schools, households, and industrial settings. Having this type of PCB is advantageous because fire causes catastrophic damage–we want to prevent that, of course. There are two popular types of smoke sensors most often used:

• Photoelectric smoke detectors
• Ionization smoke detectors

To understand their working principle of both, you need to have a clear idea about these two types of smoke detectors.

Photoelectric smoke detector circuit boards contain an LED and a light detector. Usually, photocells are used as the light detector. Photocells conduct when lights fall on them. But, they can’t work in the middle of smoke as light from the source gets interrupted.

Ionization smoke detector circuits operate differently. They contain two electrodes and an ionization chamber that is filled with ions. The movement of these ions gets interrupted in the presence of smoke. Then, the electrodes become unable to conduct ions.

These two types of detectors have Aluminum Oxide and Tin Oxide. These function to make the sensing layer of a smoke sensor circuit board.

Smoke detector PCB usually is capable of detecting LPG, Hydrogen, Methane, smoke, Butane, and many other combustible gases.

Benefits of a Detector PCB

How to Construct a Metal Detector PCB Board?

You need to arrange the following materials and parts to construct a Metal Detector PCB:

• A 9-volt battery
• Battery connector
• Slide switch
• Connecting wire
• Transistor
• Capacitor
• Resistors

These parts are required to be placed on the printed circuit board with a couple of coil wires and two batteries.

When you do this, it helps identify the frequency alteration of the oscillator that takes place. The oscillator frequency alters due to the increase of temperature and the falling of supply voltage. That’s why you should adjust the radio frequency and keep the tone at the minimum level.

Construction of a Metal Detector PCB

What Are the Basic Metal Detector PCB Types?

A Metal Detector PCB is a top-performing circuit board used to identify precious metals in the ground. They also help secure commercial and industrial areas. Usually, three basic types of Metal Detector PCB boards are used in electronic/commercial appliances.

PI Metal Detector Circuit

PI is the short form of “Pulse Induction”. In the case of the PI Metal Detector PCB board, impulses are pulled into the metal. Then, the signal impulse is reflected and distorted in the opposite direction.

This PCB identifies the metal by considering the types of distortion that happen due to impulse.

BFO Metal Detector Circuit

Beat Frequency Oscillator (BFO) metal detector circuits contain two oscillators. One of them is constant, and the other holds a resonance coil. When this PCB detects the presence of a metal, a frequency change occurs.

You can easily understand the existence of metal if you adjust the frequency. A loudspeaker or headphone is used here to deliver a signal.

TR/IB Metal Detector Circuit

This type of metal detector PCB is based on the transmission-reception-induction balance mechanism. Here, the transmitter and receiver create a coupling with an inductor. The slightest presence of metal causes alteration of induction coupling.

What Are the Differences Between Ultrasonic and PIR Motion Detector PCB?

Ultrasonic and PIR (Passive Infrared) are two widely used technologies for Motion Detector PCBs. Both of these motion sensors are reputable for reliability and accuracy. But they have some fundamental differences.

Here you get a clear idea of the fundamental difference between PIR and ultrasonic motion detector circuit boards. Let’s have a look.

Working Procedure

Ultrasonic Motion Detector PCB emits sound signals higher than the normal audible range of the human ear. These signals are reflected in the detector circuit.

A motion detector circuit holds a transducer that determines the echo and distance of the source. If the source remains within a particular periphery, this detector gives a signal.

On the contrary, PIR motion detector PCB deals with a PIR camera. It identifies IR radiation from the surroundings. When an object crosses that region, the sensor’s temperature fluctuates, and it delivers a signal to you.

Functionality

In many cases, PIR motion detector circuit boards offer better functionality than active ultrasonic motion sensor circuits. As they deal with IR and sense the temperature, PIR sensors can detect sensitive motions smoothly. But, ultrasonic technology is also popular in many applications.

Application

Ultrasonic motion detector circuits are compatible with almost all kinds of motions. There are no bindings of color, materials, etc. But, PIR sensors don’t cover a wide-scale application due to their IR sensitivity.

Reliability

Both of these sensors are reliable. But, PIR Motion Detector PCBs are more dependable. The PIR type also prevents false alarms.

PIR Motion Detector Printed Circuit Board

How Does a Leak Detector PCB Work?

Leak Detector PCB is part of prepping a Leak Detector. This PCB is mainly used in finding gas leaks. The PCB works by using soundwaves. It emits alarms when a specific frequency range is sensed.

A frequency shift is found in this circuit board when it detects a gas leak or any related substance. Then, an LED attached to the leak detector transmits signals. Then, you will get notified of of a leakage.

Leak detector circuit boards also operate the recording attachment devices. These PCBs handle the current flow reliably.

What Is a Bat Detector PCB?

Bat Detector PCB is a circuit board used to detect the high-frequency clicks of bats. Bats generate ultrasounds to move. That’s why an ultrasonic transducer is used in the bat detector circuit boards.

This PCB captures the ultrasound waves coming from the bats. Then, it generates a larger output voltage than audio microphones. Ultrasonic transducers are not very responsive to low-frequency signals. Hence, this lessens the possibility of false alarms for bat presence.

After detecting high-frequency inaudible sounds, the Bat Detector PCB converts high-frequency inaudible sounds to a lower frequency pulse. A frequency divider is used in this conversion.
