Tire pressure monitoring system TPMS solar powered Digital LCD Display Auto Security Alarm System with 4 external sensors Tire Pressure Motorcycle Monitoring System with 2 External Sensors Motor TPMS Real-time Voice Alarm Tyre Security USB Charging 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 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 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 don"'"t 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 sensors: Its 2 external sensors with IP67 waterproof grade are suitable for being used on rainy days. Besides, they are in high sensitivity and good accuracy for measuring pressure and temperature. Specifications: External sensor: - 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 Solar Power Wireless Car TPMS Tire Tyre Pressure Monitoring System with 4 External Sensors For Cars Features: 1: High accuracy, Using Freescale imported chips 2: Easy installation; 3: Environmental protection solar cells(650mAh); 4: Air pressure alarm; 5: Air leakage alarm, prevent tires from bursting; 6: Real-time monitoring tire pressure and temperature; 7: Sensor accurate wireless transmission; 8: Simple user interface; 9:Anti-theft nuts. Match sensor(charging/vent): Long press menu key"3 seconds to U/S,then short press menu key"several times to enterLID"interface,it shows ID of four tires and car icon.Short press left/right select key"to learn ID opertion.Select tire you plan to learn ID of sensor by pressmenu key,default setting is FL Product description: Solar TPMS is in the ordinary TPMS (tire pressure monitoring system) based on a flight-type upgrade, with features: real-time monitoring tire pressure, tire temperature, permanent life Thus solving the general TPMS (tire pressure monitoring system) repeated charging, occupying the cigarette mouth, occupy a series of DVD display and other deficiencies The composition of the solar TPMS is the same as that of the ordinary TPMS (tire pressure monitoring system), which is composed of a solar TFT screen receiving display and four pressure sensors / emitters. As the generous power generation panel long life, to provide at any time charging, so that the reception of the monitor power storage more robust and lasting; even in the absence of sunshine in the dark environment, rain and snow weather conditions can still serve more than 15 days, There are USB charger interface, dual charging system device to ensure that the machine really permanent life.
