About HFY Technology

Who We Are

From Shenzhen to 30+ Countries

HFY Technology (Shenzhen Huifengyuan Technology Co., Ltd.) is a Chinese supplier and engineering house focused on environmental monitoring sensors, water quality instruments and IoT systems.

For over a decade our team has delivered sensing and software projects — from single RS485 probes to nationwide monitoring networks. That experience became our product line: rugged sensors, reliable gateways and ThingsBoard-based cloud software that work out of the box, at factory-direct prices.

We speak fluent English and work with distributors, system integrators, research institutes and end users across Europe, North America, the Middle East, Southeast Asia and Latin America.

What Makes Us Different

• Engineers, not traders. We design firmware, enclosures and dashboards ourselves — when you ask a technical question, you get an engineering answer.
• Honest specs. Real measurement ranges, real accuracy classes, real IP ratings. If a low-cost part fits your project better, we'll say so.
• Long-term support. Firmware updates, spare parts and platform maintenance for years after delivery — we're on your project team, not just your invoice.
