Best quality USB Solar Charging MotorcycleMotor Vehicle Sensors Tire Pressure Tyre Temperature Monitoring Alarm System with 2 External Descriptions: Many motorcycle accidents are caused by the flat tire on the road. As a motorcycle owner, the safety of driving is the first thing. To reduce such accidents, the installation of Vehicle Sensors Tire Pressure monitoring system (TPMS) is necessary. With the TPMS, we can keep the tire working within the specified pressure and temperature range at any time to reduce the damage of the tire for safe driving. Main features: - Powerful TPMS: TPMS can monitor Vehicle Sensors Tire Pressure / temperature status in real time, which will transmit real-time voice alarm and warning indicator light to remind the driver for driving safety. - Wide compatibility: This system is widely compatible with those motorcycles with 2 tires. You dont have to worry about the compatibility issue. - Power supply: Supports USB charging, which means that you could use the USB cable (not included) to charge it up while it is in low power, rather convenient. - 2 external s: Its 2 external s with IP67 waterproof grade are suitable for being used on rainy days. Besides, they are in Vehicle Sensors high sensitivity and good accuracy for measuring pressure and temperature. Specifications: External : - Battery: built-in 140mAh button cell - Waterproof grade: IP67 - Working temperature: -30 - 80 Deg.C - Storage temperature: -30 - 85 Deg.C TPMS: - Battery: built-in 345mAh Li-ion battery - Operating voltage: 3V - Working frequency: 2.4GHz - Response time: 6s - Working humidity: 95 percent and less - Pressure monitoring range: 100 - 900 kPa - Pressure accuracy: minus or plus 10 kPa Descriptions: This Vehicle Sensors Tire Pressure monitoring system is designed to provide you with an extra protection while driving. It will warn the tire condition of the car in advance. After installing TPMS, it can monitor the Vehicle Sensors Tire Pressure and temperature in real time. If abnormal Vehicle Sensors Tire Pressure and temperature are detected, the system will send real-time warning sounds and flashing icons on screen to inform you, avoiding traffic accidents.
