Development of Infrared Therapy Device Based on Android Application Using Bluetooth Communication to Minimize the Patient Contact

Infrared therapy is a therapeutic tool that has the function of dilating blood vessels so flow becomes smoother and healing process wounds or inflammation in body faster. The heat from infrared lamps can also reduce joint muscle pain. purpose this research to design an device equipped with light intensity settings timer controlled by android. contribution lamp irradiation media system been safe distance 30-70cm using HC-SR04 sensor, then choice maximum time 10-30 minutes which used select length process. In addition, it adjust as needed via Android connected HC-05 Bluetooth module enabled regulate how much emitted lamp. After carrying out measurement process, error value on obtained selection Low, Medium, High switches, 10 (1%), 15 (0.6%), 30 (0.3%). measurements are, 10cm (10%), 20cm (2.5%), 30cm (1.6%), 40cm (0%), 50cm (4%), 60cm 70cm (0%).
