Diabetes is one of the most life-threatening disease prevalent in human beings. To control Diabetes, the blood sugar level of the individual must be checked regularly. The present methods available in the market to measure blood sugar makes use of invasive techniques, a prick is done on the finger and blood sample is taken for measurement. This process is painful and is not cost effective. Non-invasive method can be used which facilitates frequent testing, relieves pain and discomfort caused by frequent finger pricks. A Non-invasive method of glucose level measurement is proposed. The variation in the intensity of NIR light received from the photo detector after passing through the finger is used to determine the glucose level of blood. The measured glucose level is displayed in LCD display and also transmitted to the android application which is created in the mobile phone to display and store data via Bluetooth.
