    ultrasonic sensor

    Bring your automation and robotics projects to life with the HC-SR04 Ultrasonic Distance Sensor. Operating much like sonar, this module sends out a high-frequency sound wave and measures the time it takes for the echo to bounce back, calculating exact distances with impressive precision.

    Whether you are building an obstacle-avoidance robot, a smart parking assistant, or an automated liquid level indicator, this sensor provides reliable, real-time data.

    Key Features & Technical Specifications:

    • Operating Voltage: $5\text{V DC}$

    • Quiescent Current: Less than $2\text{mA}$

    • Effectual Angle: $< 15^\circ$

    • Detection Range: $2\text{cm} - 400\text{cm}$ ($1\text{ inch} - 13\text{ feet}$)

    • High Precision: Accurate down to $0.3\text{cm}$

    • Input Trigger Signal: $10\mu\text{s}$ TTL impulse

    • Easy 4-Pin Interface: VCC ($5\text{V}$), Trig (Trigger Input), Echo (Receive Output), and GND (Ground).

    Why Choose the HC-SR04 Module?

    • Breadboard Friendly: Easily plugs into standard breadboards for quick prototyping without messy soldering.

    • Widely Supported: Fully compatible with standard Arduino IDE libraries, making code setup quick and effortless for beginners and pros alike.

    • Stable Performance: Features compact onboard processing crystals to ensure steady, reliable readings under varying project conditions.

    tv indoor antenna

    • Heavy-Duty Magnetic Base: The powerful magnetic bottom allows you to instantly mount the antenna onto any iron or steel surface—such as the back of your TV frame, metal window frames, iron security grilles, or file cabinets. This significantly improves signal stability and prevents the antenna from tipping over.

    • 360-Degree Omni-Directional Reception: No need to constantly adjust or point it in one exact direction. It pulls in frequencies from all sides, making it much easier to lock onto broadcasting towers.

    • Compact & Discreet Design: Say goodbye to ugly, massive "rabbit ears." Its sleek, space-saving vertical wand design blends seamlessly next to your smart TV or decoder setup without cluttering your living room.

    • Plug-and-Play Setup: Comes equipped with a long, high-quality coaxial cable. Simply screw it into your TV’s "Antenna In" or your digital decoder box, run a quick channel scan, and start watching.
