The SPC HC-SR04 ultrasonic sensor SEN-US01 distance measuring module is compared with other SPC brand products from completely different categories: the Connection Piece with Joint SPC DUCO D180/D160 (M/M) duct transition adapter, the Facial Cleansing Device SPC BE-100124, the Siphon flat SPC DUCO (Energy & Eco) floor drain siphon, and the Humidity Room Sensor SPC DUCO with Control. Since these items serve fundamentally different purposes, they share only the SPC brand, while their intended use, practical application, and technical nature are entirely unique.
⚙️ The specification and parameter comparison covers the product type, primary purpose, compatibility, and application context.
| Comparison parameter | SPC HC-SR04 (distance sensor) | Connection Piece with Joint SPC DUCO D180/D160 | Facial Cleansing Device SPC BE-100124 | Siphon flat SPC DUCO | Humidity Room Sensor SPC DUCO | Practical significance |
|---|
| Product type | Electronic module for microcontrollers | HVAC duct adapter | Facial cleansing skincare device | Plumbing drain siphon | Indoor humidity sensor | Each product belongs to an entirely separate technical domain and cannot substitute another. |
| Primary purpose | Precise non-contact distance measurement | Connecting circular ventilation ducts | Daily skin hygiene and facial cleansing | Wastewater drainage in wet areas | Measuring and controlling indoor humidity | Application areas differ completely: spanning electronics, HVAC, plumbing, and personal care. |
| Application field | Robotics and electronics automation | Ventilation and air distribution systems | Home skincare and personal hygiene | Building renovation and bathroom plumbing | Building automation and climate control | The choice depends entirely on the specific engineering, home improvement, or personal care task. |
◎ The evaluation of use cases and buyer needs helps identify the right application scenarios for each compared product.
| Use case | Recommended product | Why |
|---|
| Building robots and microcontroller projects | SPC HC-SR04 ultrasonic sensor SEN-US01 | The module is specifically designed for precise distance measurement and obstacle detection in electronics. |
| Installing ventilation and joining circular ducts | Connection Piece with Joint SPC DUCO D180/D160 | Engineered to connect ventilation ducts of differing diameters with a secure mechanical joint. |
| Skincare and daily hygiene routines | Facial Cleansing Device SPC BE-100124 | Designed to provide mechanical facial cleansing and improve skin freshness at home or while traveling. |
| Drainage installations in tight spaces | Siphon flat SPC DUCO (Energy & Eco) | Features a low-profile design tailored for concealed or minimal-height shower and wet area drainage. |
| Indoor climate monitoring and ventilation control | Humidity Room Sensor SPC DUCO with Control | Measures relative humidity and integrates with ventilation systems for automated indoor climate regulation. |
The SPC HC-SR04 ultrasonic sensor SEN-US01 differs fundamentally from the other evaluated SPC items because it is an electronics component for microcontrollers, whereas the alternatives focus on ventilation, plumbing, and personal care. This sensor is ideally suited for electronics hobbyists and robotics developers, and a buyer will choose it over the alternatives specifically when requiring non-contact distance measurement and automation capabilities.
