Car Tire Pressure Monitoring System Cigarette Lighter Plug TPMS LCD Display Waterproof 4 External Internal Sensors USB Charging

Description:   Many accidents are caused by the flat tire on the highway. As a car owner, the safety of driving is the most important. To reduce such accidents, the 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:    - Directly powered by the cigarette lighter, very convenient - The 2A USB charging port for phone or other electronic devices charging - With a digital screen displaying the car tire pressure and temperature simultaneously, simple and intuitive - Freely switch pressure units (bar / psi), temperature units (Deg.C / Deg.F) - 4 external sensors are also suitable for any weather, they are in high sensitivity and good accuracy for measuring pressure and temperature   Specifications:   TPMS - Working voltage: DC 5V - Working current: 16mA and less - Working temperature: -20 - 60 Deg.C - USB output: 5V, 2A - Transmission frequency: 433.92MHz - Sensitivity: less than -105dBm - Pressure unit: psi / bar - Temperature unit: Deg.C / Deg.F - Power supply: cigarette lighter     External Sensors   - Standby current: less than 0.7uA - Transmission current: less than 8mA - Pressure measuring range: 0 - 3.5 bar - Temperature measuring range: -20 - 50 Deg.C - Accuracy: + / - 4 Deg.C - Working temperature: -20 - 60 Deg.C - Battery: CR1632 3V 120mAh button cell (built-in) - Battery life: 1 - 2 years     Internal Sensor - Standby current: less than 0.7uA - Transmission current: less than 10mA - Pressure measuring range: 0 - 3.5 bar - Temperature measuring range: 0 - 70 Deg.C - Accuracy: + / - 3 Deg.C - Working temperature: -40 - 125 Deg.C - Battery: CR2025 3V 330mAh button cell (built-in) - Battery life: 3 - 5 years
