Bluetooth Tire Pressure Monitor 4PCS Set with APP Control and IP67 Waterproof Rating

Enhance vehicle safety with this comprehensive four-sensor tire pressure monitoring system designed for modern drivers. Utilizing Bluetooth 5.0 technology, the system transmits precise pressure data directly to a smartphone application, eliminating the need for manual gauge checks. The external sensors feature a robust IP67 waterproof construction, ensuring reliable performance in rain, snow, and dusty environments. With a wide operating temperature range from -30°C to +70°C, these monitors maintain accuracy in extreme climates. The low-power design supports a battery life of 2 to 3 years, providing long-term peace of mind without complex maintenance routines.

Technical Specifications

The system is engineered for precision and compatibility, utilising the SY36201 master control for stable data transmission. Key technical details ensure the device meets rigorous automotive standards for reliability and response speed.

Connectivity and Response

Equipped with Bluetooth 5.0, the monitor connects seamlessly to mobile devices within the 2.4GHz frequency band. The system boasts a rapid response time of less than 4 seconds, ensuring that pressure changes are reflected on the APP interface almost instantly. Transmission power is set at 4dB to maintain a stable connection while conserving energy, with a static current draw of ≤1uA when idle to maximise battery efficiency.

Pressure Accuracy and Range

The sensors cover a monitoring range of 0 to 100PSI, suitable for most passenger vehicles and light trucks. Data accuracy is maintained within a margin of ±3PSI, providing sufficient precision for daily safety checks. The APP-style display allows users to visualise data clearly, making it easier to identify under-inflated tyres before they become a hazard.

Power and Battery Life

Each sensor is powered by a 140mAh external battery cell, optimised for low energy consumption. The working voltage operates between 2.1V and 3.3V, ensuring stable function throughout the battery's life. Users can expect a battery lifespan of approximately 2 to 3 years under normal driving conditions, reducing the frequency of sensor replacement.

Durability and Design

Built to withstand the rigours of the road, the physical construction of these monitors prioritises resilience against environmental factors. The compact black design blends with most wheel aesthetics while providing robust protection.

Waterproof and Weatherproof

With an IP67 waterproof grade, the sensors are fully protected against dust ingress and can withstand immersion in water up to 1 metre for 30 minutes. This rating ensures functionality during heavy rainstorms, car washes, and muddy off-road conditions. The operating humidity tolerance reaches up to 95% MAX, preventing internal corrosion from moisture.

Temperature Resistance

The device is tested to function reliably in storage and working temperatures ranging from -30°C to +70°C. This wide thermal tolerance prevents failure in freezing winter conditions or during hot summer drives when tyre temperatures can rise significantly due to road friction.

Physical Build

Each unit weighs only 20g, minimising any potential imbalance on the wheel rim. The external mounting style allows for easy installation on standard tyre valves without the need for inside-the-wheel setup. The black casing is designed to resist UV degradation and physical impact from road debris.

Installation and Usage

Setting up the system requires no professional tools, making it accessible for all vehicle owners. The process involves simple physical installation followed by a quick digital pairing sequence.

Simple Setup Process

Begin by screwing the four external sensors onto the tyre valves. Ensure they are tightened securely to prevent air leakage. Once installed, download the compatible APP on your smartphone and enable Bluetooth. The system will detect the sensors within seconds, displaying the current pressure for all four tyres on the screen.

Daily Monitoring Benefits

Regular use of this monitor helps maintain optimal fuel efficiency and extends tyre lifespan by ensuring correct inflation. The instant alerts provided by the APP allow drivers to address pressure loss immediately, reducing the risk of blowouts. The silent background operation means the system works continuously without distracting the driver from the road.
