有關 英語 (美國) 的問題

I am not sure that the essay I write below is totally grammatical. Can you give me any advice? Thanks in advance! ^^

The elderly can get the condition of their body from some body parameters like heart rate and blood pressure. These parameters can be measured by electronic sensors conveniently. For instance, my grandfather suffers from high blood pressure, a common disease among the elderly. With an electronic device, it is easy for him to measure the blood pressure by himself. What he needs to do is just to wrap the cotton cloth containing the sensor around his left or right arm and put the bottom, then the digit of blood pressure will be on the screen of the device within one minute. On the contrary, if he doesn't learn how to use the electronic device, the new thing, it will cost him much time to go the hospital to ask the doctors for help.
