Infrared PIR Motion Sensor Switch
An Infrared PIR Motion Sensor Switch is an electronic device that detects movement by sensing changes in infrared (IR) radiation in its field of view. "PIR" stands for Passive Infrared, meaning it doesn't emit any energy itself but rather passively monitors the infrared radiation given off by objects. 🌡️ How it Works At the core of a PIR sensor is a pyroelectric sensor, which is sensitive to heat (infrared radiation). Most PIR sensors have two halves, or "slots," wired in a differential arrangement. Here's a simplified breakdown of its operation:- Idle State: When there's no movement, both halves of the sensor detect the same amount of ambient infrared radiation from the surroundings.
- Motion Detection: When a warm object, like a human or animal, moves into the sensor's field of view, it first intercepts one half of the sensor, creating a temporary difference in the infrared radiation detected by the two halves. This difference generates a voltage pulse.
- Signal Processing: The sensor's circuitry processes this voltage pulse. If the change is significant and matches the pattern of a moving heat source, the sensor triggers an output signal.
- Fresnel Lens: A key component of a PIR sensor is the Fresnel lens . This specially designed plastic lens focuses infrared radiation from different angles onto the pyroelectric sensor, effectively dividing the detection area into multiple sensitive zones. This allows the sensor to have a wider field of view and detect movement more effectively.
- Automatic Lighting Control: This is one of the most common applications. PIR sensors turn lights on when someone enters a room, hallway, or outdoor area and turn them off after a set period of no motion, saving energy.
- Security Systems: They are integral to security alarms, detecting intruders and triggering alerts or security cameras.
- Smart Home Systems: PIR sensors play a role in smart homes for automating various functions, from lighting and HVAC systems to controlling appliances based on occupancy.
- Automatic Doors: In public buildings, they detect approaching individuals to automatically open doors.
- Energy Management: By ensuring that lights, HVAC, and other devices only operate when an area is occupied, PIR sensors contribute significantly to energy savings in residential and commercial settings.
- Wildlife Tracking and Research: Researchers use them to monitor animal movements without disturbance.

Power converters – AC 24 V to DC 15 V
Ship or pick up from our office.
Power converters - AC 24 V to DC 15 V
A "Power converter - AC 24 V to DC 15 V" is a device that transforms an alternating current (AC) input of 24 volts into a direct current (DC) output of 15 volts. Here's a breakdown of what that means and how it works: AC (Alternating Current): This is the type of electricity typically supplied by wall outlets in homes and businesses. The voltage constantly changes direction, flowing back and forth. 24V AC is a common voltage for certain low-voltage control systems, industrial equipment, and sometimes HVAC systems. DC (Direct Current): This is the type of electricity that flows in only one direction. Most electronic devices, like phones, laptops, and many sensors or control circuits, require DC power. How an AC to DC Converter Works: An AC to DC converter (also known as a rectifier or power supply) typically involves several stages:- Step-Down Transformer: The initial 24V AC is usually too high for direct conversion to 15V DC. A transformer "steps down" this AC voltage to a lower, more manageable AC voltage.
- Rectification: This is the core of the AC to DC conversion. Diodes are used to convert the alternating current into a pulsating direct current. There are different types of rectifiers (half-wave, full-wave, bridge) that achieve this with varying degrees of efficiency and ripple.
- Smoothing (Filtering): The pulsating DC output from the rectifier isn't perfectly smooth. Capacitors are used to "smooth out" these ripples, creating a more stable DC voltage.
- Regulation: To ensure a precise and constant 15V DC output, a voltage regulator is often employed. This circuit maintains the output voltage at the desired level, even if the input voltage fluctuates or the load on the power supply changes.
- Industrial control systems: Powering sensors, actuators, and control circuits that operate on 15VDC.
- HVAC systems: Often 24VAC is used for thermostats and control panels, but some components within the system might require 15VDC.
- Security systems: Powering cameras, access control devices, and other equipment.
- Lighting systems: Especially in specialized LED lighting setups.
- Custom electronics projects: Where a stable 15VDC is needed from an existing 24VAC infrastructure.
- Output current (Amps): How much current the connected device needs.
- Power rating (Watts): The total power the converter can deliver.
- Efficiency: How much energy is lost during the conversion process (higher efficiency means less heat and less wasted energy).
- Protection features: Over-voltage, over-current, short-circuit protection for safety and device longevity.
- Form factor: Whether it's an open-frame, enclosed, or DIN-rail mount design.

Power converter – AC 24 V to DC 12 V
Ship or pick up from our office.
Power converter - AC 24 V to DC 12 V
A power converter - AC 24 V to DC 12 V is a device that transforms alternating current (AC) at 24 volts into direct current (DC) at 12 volts. These are also commonly referred to as AC/DC power adapters or rectifiers. How it Works ⚙️ The conversion process from AC to DC typically involves several key stages:- Step-Down Transformer: The 24V AC input first goes through a transformer. This component reduces the voltage from 24V AC to a lower AC voltage, although not necessarily directly to 12V DC at this stage. It's about getting to a more manageable voltage level for the subsequent steps.
- Rectification: The reduced AC voltage then enters a rectifier circuit, usually made of diodes. Diodes allow current to flow in only one direction, effectively converting the alternating current (which periodically reverses direction) into a pulsating direct current (which flows in one direction but isn't smooth).
- Half-wave rectifiers block half of the AC waveform.
- Full-wave rectifiers (like a bridge rectifier) use both halves of the AC waveform, resulting in a smoother, more efficient conversion.
- Smoothing (Filtering): The pulsating DC output from the rectifier isn't perfectly steady. It has "ripples" or fluctuations. To smooth this out, capacitors are used. These components store electrical energy during the peaks of the waveform and release it during the dips, creating a much more stable and continuous DC voltage.
- Voltage Regulation: Finally, a voltage regulator circuit ensures that the output voltage remains consistently at the desired 12V DC, regardless of minor fluctuations in the input AC voltage or changes in the load connected to the converter. This also helps protect the connected device from voltage spikes or drops.
- CCTV cameras and surveillance systems: Many security cameras operate on 12V DC, and these converters allow them to be powered from a 24V AC power supply (which is often used in larger installations for longer cable runs due to less voltage drop).
- Low-voltage lighting: Converting 24V AC to 12V DC for certain LED lights or other low-voltage lighting systems.
- Industrial control systems: Some industrial equipment or sensors might use 12V DC power while the facility's power supply is 24V AC.
- Automotive accessories (with specific input needs): While most car systems are 12V DC, there might be niche applications where a 24V AC source needs to be converted.
- Various electronic projects and devices that require a stable 12V DC supply from an AC input.
