Function Declaration is Incompatible Between .h and .c Files After the Introduction of External Typedef Struct

I've split up my program into different .c and .h. files with functions in .c and function prototypes, structs and typedefs in the .h files.

Let's say I have car.c and car.h. These include functions that take in a Sensor* sensor however Sensor is a typedef struct from sensor.h. So I simply write #include "sensor.h" in car.h. Now both car.c and car.h have access to Sensor and my IDE seems to confirm that.

The problem arises from the functions themselves that argue Sensor* sensor. Let's say I have void printCarSensors(Sensor* sensor1, Sensor* sensor2) {}. Both car.c and car.h will be happy with the Sensor* type. car.c will be entirely happy, no errors at all.

However, car.h will have a red line under printCarSensors and the error will be:

declaration is incompatible with "void printCarSensors(Sensor* sensor1,
Sensor* sensor2) " (declared at line 26 of "C:\Users\user\Desktop
WorkingFiles\car.c")

In sensor.h I would have

typedef struct sensor Sensor;

struct sensor{
    int time;
    int speed;
    int acceleration;
    int temp;
};

Hopefully that all makes sense and any help would be greatly appreciated.
