The pediatric CPR training kit (for children aged 1–8 years) consists of a diagram of a child within this age range for practicing CPR, along with a chest-compression module made of natural rubber. Inside the module, sensors are installed to measure compression force, which is processed by a microcontroller. The system produces an audio signal through a buzzer each time an adequate compression force—based on the preset value—is achieved. It also displays the compression time and count on a 20×4-
