How to pass data from DHT11sensor (temperature&humidity Sensor) using Arduino software to Constant Block in Simulink?

hellos everyone . I am now working on a project that is the regulation of the temperautre and humidity with the help of the Arduino + DHT11 sensor and Simulink , I connected a script matlab in series with the Arduino software to extract values humidity and temperature to plots them in a graph. I'd like to display these values in Simulik for the regulation of these values ,I got Many problem at the declaration of set- param function here is the matlab code (exemple Temperature ):

s = serial ( 'COM5');

temps=1000;

i=1;

fopen(s);

while(i<temps)

fprintf(s, 'information de communication série');

out = fscanf(s)

global Temp ;

Temp(i) = str2num(out(1:4));

 set_param('DHT11SIM','Temperature','value',num2str(Temp))
  set_param('DHT11SIM', 'Temperature', 'update')

subplot(211);

plot(Temp,'g');

axis([0,temps,20,50]);

title('DHT11 Température');

xlabel('---> temps (secondes)');

ylabel('---> Température');

grid

code simulink:

here is the erruer thatI I always receives: Error using DHT (line 15) Invalid Simulink object name: DHT11SIM/Temperature .

please Help me
