@Shubham_Thakur Sir if you have 4 tf lina then you will go with I2C communication. First using this link Download and configure your 4 number of TF luna according into above link manual and data sheet. assign different I2C address for each TF luna. connect all 4 sensor to I2C splitter(i am in india, you can go with yours possibility).
