Automotive sensing
Parking sensors, tyre pressure monitoring and mmWave radar for passenger cars and light EVs.
Sensors built to their datasheet.
Ultrasonic, radar, pressure and inertial sensors, made in Guangzhou to IATF 16949.
Start with what you measure
Four divisions, one catalog. Every model has a full specification table and a PDF datasheet.
Distance and level
Ultrasonic and laser sensors that measure range, fill level and height, in air or under water.
Pressure, temperature and motion
Pressure and level transmitters, temperature sensors and inertial sensors for plants and machines.
IoT monitoring
Battery-powered wireless sensors and systems that report pressure, tilt and position remotely.

Your spec, our production line
When no catalog model fits, we adapt one: housing, cable, interface, firmware, range.
Requirement review
You send the target, environment, interface and volume. Engineering confirms feasibility.
Samples
We adapt an existing design and build samples for your bench and field tests.
Validation
Environmental and reliability tests, then a sign-off on the final specification.
Production
Series production on our IATF 16949 lines with every unit inspected.

Frequently asked questions
FAQWhat sensors does DWIN make?
DWIN makes ultrasonic parking sensors, tyre pressure monitoring systems and 77 to 81 GHz mmWave radar for vehicles; ultrasonic distance, level and underwater sensors; laser distance sensors; pressure and level transmitters; inertial sensors; and IoT monitoring systems.
Where is DWIN located?
DWIN, Guangzhou Dwin Technology Co., Ltd., is in Dongyong Town, Nansha District, Guangzhou, Guangdong, China. The plant and the sales team are at the same site.
Which quality certifications does DWIN hold?
DWIN works under ISO 9001 quality management, IATF 16949 automotive quality management and ISO 14001 environmental management. Product approvals such as CE, E-Mark, FCC, RoHS, REACH and UL are held for specific models; ask sales for the certificate of your model.
Can DWIN customise a sensor for my product?
Yes. We adapt housing, cable and connector, interface and protocol, firmware, range and blind zone from an existing design, then build samples for your tests before series production.
