The less text, the more informative... A complete in-vehicle IoT device solution.
Like this post to stay on track! BF
product features
include an IoT positioning module with remote control. This solution is also compatible with various communication protocols such as 485, Modbus, MQTT, TCP, and UDP. It features
vibration sensing, automatic sleep mode when stationary, and automatic wake-up upon vibration. When
the power supply voltage drops below 10V, it will automatically shut down 4G communication and GPS power supply, and the load will also be turned off to protect the vehicle battery. Upon voltage recovery, it will automatically connect to the network and send its location.
It includes GPS signal loss detection and cloud data feedback.
Vehicle control functions include remote start, remote unlock, remote fuel cut-off, power cut-off, etc.
The load can control multiple lighting modes (strobe, breathing, navigation, single flash, double flash, etc.).
It can be expanded with the CAN protocol for advanced remote vehicle control functions (protocol requirements analysis required).
