Ultrasonic Sensor 40KHZ Transmitter Receiver
Br 400.00
- The 1040 open-type ultrasonic sensor with an “R” designation is a 40 kHz piezoelectric receiver component designed to detect incoming sound waves. It works alongside a matching transmitter (“T”) for object detection and distance measurement.
- 10mm Ultrasonic Sensor Transmitter and Receiver Pair (40kHz)
- Component Type: Raw Ultrasonic Transducer Pair (1 Transmitter, 1 Receiver)
- Diameter: 10mm (Compact Form Factor)
- Center Frequency: 40.0 ± 1.0 kHz
- Bandwidth: 2.0 kHz (-6dB)
- Sound Pressure Level (Tx): ≥ 112dB (at 10Vrms, 30cm)
- Sensitivity (Rx): ≥ -70dB (at 40kHz)
- Capacitance: 2000pF ± 20%
- Housing Material: Aluminum (Open Type – Indoor Use)
- Directivity (Beam Angle): ~60° to 80°
- Operating Temperature: -20°C to +70°C
- The 10mm Transducer Pair unlocks Custom Acoustic Design. By building your own amplification and driving circuit (using Op-Amps like LM358 or specific driver ICs), you can adjust the gain, pulse width, and sensitivity to suit your specific environment.
- 10mm Ultrasonic Sensor 40KHZ Transmitter Receiver
- This is 10mm Ultrasonic Transducer Pair (Tx+Rx). If you have ever tried to squeeze a bulky HC-SR04 module into a sleek 3D-printed enclosure or a tiny drone frame, you know the struggle. Standard 16mm sensors are great, but they often dominate the design.
- The 10mm Ultrasonic Transducer Pair (Tx+Rx) is the compact solution for engineers who need to shrink their footprint without sacrificing performance. This set includes matched Transmitter (T) and Receiver (R) units, precisely tuned to 40kHz. Unlike pre-assembled modules, these raw components give you total control over your driving circuitry, allowing you to design custom range finders that fit your specific mechanical constraints. Whether you are building a micro-mouse robot or a discrete liquid level monitor, these sensors deliver high sensitivity in a significantly smaller package.
- T (Transmitter): Usually marked with a ‘T’ on the underside. This unit sends the pulse.
- R (Receiver): Marked with an ‘R’. This unit listens for the echo.
- Effort Level: Advanced. Requires knowledge of analog electronics (Op-Amps, Signal Filtering).
- Minimum Hardware: You will need an oscillating circuit (to drive the Tx) and an amplifier circuit (to read the Rx).
Applications
- Micro-Robotics: Ideal for “Sumo” or “Micro-Mouse” robots where every millimeter of frontal area counts.
- Custom PCB Integration: Embed distance sensing directly into your motherboard instead of using daughter boards.
- Liquid Level Sensing: Non-contact measurement for small tanks or dispensers.
- Object Detection: Invisible “tripwire” security systems.
- Gesture Control: Create short-range hand wave interfaces.
