The quality Built-in Pressure Sensor developed by Zhaofeng factory is a miniature intelligent sensor powered by a 3V lithium battery, integrating pressure and temperature measurement functions with wireless radio frequency communication capabilities. It transmits detected data to a receiver via wireless communication to monitor tire pressure and temperature status in real time. When abnormalities such as high pressure, low pressure, leakage, or high temperature occur, it alarms through sound and light to remind users to handle the situation promptly, thereby avoiding driving safety hazards. It is compatible with most vehicle models and can be installed and used quickly without complex debugging.

Our Built-in Pressure Sensors, featuring ultra-low power consumption design and industrial-grade lithium thionyl chloride batteries, operate stably even in extreme temperatures ranging from -40°C to 125°C, delivering a maintenance-free service life of 5-10 years and eliminating the hassle of frequent replacements for users. With high-precision measurement capability of ±1.5 PSI, with its high-precision measurement capability of ±1.5 PSI, it can sensitively capture the phenomenon of slow tire leakage. Imagine this: before long-distance highway driving or outings in freezing winter, the sensor issues an early warning of insufficient tire pressure, allowing you to inflate the tires in time and avoid potential risks. Its IP67-rated waterproof and dustproof rugged casing is undaunted by the harsh environment inside the tire. The result is: significantly saving fuel and tire maintenance costs for fleet managers, and providing family users with all-weather peace of mind, truly transforming safety from 'passive response' to 'active prevention'.
As professional manufacturers of Built-in Pressure Sensor, we possess standardized production facilities and a rigorous quality control system. Our products have obtained ISO/TS 16949 automotive industry quality management system certification, CE certification, and TUV certification, meeting global mainstream market quality standards and environmental requirements to ensure product reliability and compliance. Throughout the production process, from raw material procurement, chip packaging, potting and sealing to finished product assembly, each procedure undergoes strict inspection. Before finished products leave the factory, they must pass multiple stringent tests, including high and low temperature testing, waterproof and dustproof testing, vibration testing, pressure accuracy testing, and wireless transmission testing. Products that fail these tests are strictly prohibited from leaving the factory. We promise that all 3V tire pressure sensors use high-quality raw materials and imported chips, refusing refurbished chips and inferior batteries to ensure product lifespan and stable performance.
