DC 5V Waterproof Ultrasonic Module Distance Measuring Transducer Sensor (waterproof ultrasonic)
Description:

This waterproof ultrasonic distance sensor is for those applications that are a bit more rugged! 25cm - 450cm sensing range.

We have used the HC-SR04 Ultrasonic Distance Sensor many times  and for many good reasons. It is pretty easy to use, it performs well, and it is very inexpensive. For collision avoidance robots or intruder detection, this sensor is usually all you’ll need.

However, using the HC-SR04 outside is a different story. It is a pretty fragile device and can easily be damaged by dirt, or even high winds. And, above all, it is not waterproof.

For these circumstances you can use this sensor, in more weathered states, even outdoors

Specifications:

Operating voltage: DC 5V
Total current work: 40mA
Acoustic emission frequency: 40khz
Maximum distance: 4.5m
Blind: 25cm

Wiring:
5V (positive power supply)
Trig (control side) RX
Echo (the receiver) TX
GND (negative)

Resolution: about 0.5cm
Angle: 70 degrees
Working temperature: -10 ~ 70 ℃
Storage temperature: -20 ~ 80 ℃

Product Features:

- small size, easy to use;
- low voltage, low power consumption;
- high accuracy;
- strong anti-jamming;
- integrated with wire enclosed waterproof probe, suitable for wet, harsh measuring conditions.

Application:

1 Horizontal distance;
2 obstacle avoidance, automatic control;
3 traffic control;
4 security, industrial control;
5 artificial intelligence, and research

Basic working principle:


(1) using IO port TRIG trigger location, to the high level signal of at least 10us;
(2) module automatically sends 8 40KHz pulse, automatic detecting whether a signal returns;
(3) on signal return, a high level is output through the IO port ECHO, the time duration of the high level is ultrasonic from launch to return. The test distance = (high level time * speed of sound (340M/S)) /2;

Grove - Ultrasonic Ranger (Grove ultrasonic sensor)
Description:

This Grove-ultrasonic sensor is a non-contact distance measurement module which is compatible with the Grove system. It's designed for easy modular project usage with industrial performance. It can measure from 3cm to 350cm with the accuracy up to 2mm. It is a perfect ultrasonic module for distance measurement, proximity sensors, and ultrasonic detector.

Compared with traditional ultrasonic modules HC-SR04, this module integrates a single-chip microcomputer, and the transmitting signal and the receiving signal share one pin by time division multiplexing, so only one I/O pin is occupied. Another difference is that HC-SR04 only supports 5V voltage, while this module supports 5V and 3.3V. As we know, the Raspberry pi I/O only supports 3.3V. Therefore, this Grove - Ultrasonic Distance Sensor can be directly connected to the I/O of the Raspberry Pi, but HC-SR04 needs to use a voltage conversion circuit.

Features:
  • 3.3V / 5V compatible, wide voltage level: 3.2V~5.2V
  • Only 3 pins needed, save I/O resources
  • Wide measurement range: 3cm ~ 350cm
  • Easy to use: grove connector, plug and play
  • Arduino library ready

Specifications:

  • Operating Voltage: 3.2~5.2V
  • Operating Current: 8mA
  • Ultrasonic Frequency: 40kHz
  • Measuring Range: 3cm to 350cm
  • Resolution: 1cm
  • Measurement Angle: 15 degree
  • Dimensions: 50mm x 25mm x 16mm
For all Grove users (especially beginners), there is guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before you use the product.

3V-5.5V HC-SR04P Ultrasonic Ranging Module (sensor ultrasonic 3V)
Description:

Ultrasonic Range finder has been very useful in many electronic project. It is low cost and teaches us the propagation of sound wave, learning about science while completing your project:) While it is popular, HC-SR04 ultrasonic sensor is 5V operated, so it is difficult to be used with 3.3V system like NodeMCU, Wemos, Raspberry pi, micro:bit or 3.3V Arduino board. No more waiting, we bring you the 3.0V to 5.5V Ultrasonic Ranging Module.

Using your echo-location abilities to detect tasty fish treats. Until genetic modifications catches up with our desires, we'll just have to make do with these handy 3V Ultrasonic Sonar Distance Sensor and a pair of flippers. These ubiquitous sensors are really common in robotics projects, but they can also be used for automation, interactive art and motion sensing. They work at about 2cm to 450cm(5V) or 400cm(3V) away, but we think 10cm-250cm will get you the best results.



These sensors are fast, fairly easy to use, and low cost. Unlike the more common HC-SR04 series, this model can be powered by 3V or 5V and the logic level will be the same. This makes this model great for use with just about any microcontroller or microcomputer. And, its HC-SR04 software compatible so just plug it in and it works the same! (Note the size is different from the HC-SR04 so you may need to make mounting adjustments)

Of course you can also use with 5V system such as Arduino UNO, Arduino Mini and Maker UNO.

Features:

  • Voltage: 3V - 5.5VDC
  • Current: 2.2mA
  • Measuring Range: 2cm - 450cm
  • Working Temperature: 0ºC to 70ºC
  • Compatible with HC-SR04 Ultrasonic Sonar Distance Sensor
  • Properly labelled pin assignment
  • Arduino and Raspberry Pi compatible
