The IoT project task is to solve a problem using an instrumentation device. Health and development of youth is extremely important. As technology improves, the ways to monitor health increase. For this project, we designed a baby monitor complete with a PIR motion sensor, sealed temperature sensor and the appropriate notifications/alarms. The idea is to supplement other monitoring tools, leading to a creative and safe way to keeping an eye on loved ones.
How It Works
Using designated parameters, the photons will respond to temperature and motion. The PIR motion sensor will send a notification through the Blynk App to phone users indicating that no motion has occurred in the last 30 seconds. In addition to the phone notification, a Piezo Buzzer fitted to the second photon will sound an alarm. The temperature sensor will monitor a mixture of body and ambient temperature near the baby. The temperature sensor will send a notification to the phone if the temperature is outside our designated range of 90 to 100*F.
As pictured, one photon is fitted with the PIR sensor, temperature sensor, and an LED to monitor the baby. The other photon is fitted with an alarm that has a stop button to notify the user.

A secondary source to record and view data is through the Blynk app. This app allows the use of widgets to determine incoming data and creating notifications when data records certain criteria. It shows a single value display of both temperature and motion and a live feed chart over time of each variable. When parameters of no motion for 30 seconds and a temperature between 90-100 degrees Fahrenheit are reached a notification will be sent to the phone.
