Pillsense: Designing A Medication Adherence Monitoring System Using Pill Bottle-mounted Wireless Sensors

In modern society, busy life has made people forget many things in day-to-day life. The elderly people and the people victims of chronicle diseases who need to take the medicines timely without missing are suffering from dementia, which is forgetting things in their daily routine. There are occasions when patients remember to take medicines at the stipulated time but forget which pill has to be taken at that particular time. It is difficult for doctors/paramedics/attenders to monitor patients round the clock. In order to avoid these problems, we have implemented this patient medicine reminder system. The system allows the user to enter the prescribed timings, at which the patient has to take the medication. This data will be stored in the EEPROM by the microcontroller. The microcontroller continuously reads the time from the RTC. When the timings read from the RTC equals the timings stored in the EEPROM, the system displays the list of medicines to be taken at that particular prescribed time on the LCD and LED corresponding to that medicine will glow. Here we are placing IR sensor in the Pill Box to check whether the person taken medicine or not. If the person open the bottle then the IR sensor stops detecting so that we can confirm that person taken medicine and if the sensor is detecting in the time then a SMS alert will be sent to the concerned person that the medicine is not taken and a buzzer will be start.
