The impact when a motorcyclist involves a high-speed accident without wearing a helmet is very dangerous and can cause fatality. Using a helmet can reduce impact impact and can save a life. There are many countries that enforce a regulation that requires the motorcycle rider to wear a helmet when riding their motorcycle, Malaysia is an example. For this reason, this project is specially developed to improve the safety of the motorcycle rider. The rider will be alarmed when the speed limit is exceeded. A force detection resistor (FSR) and a BLDC fan are used for detecting the cyclist's head and detecting the speed of the motorcycle, respectively. A 315 MHz radiofrequency module as a wireless link that is capable of communicating between the transmitting circuit and the receiving circuit. PIC16F84a is a microcontroller for controlling the entire system component. Only when the rider bent the helmet, then only the motorcycle engine will start. An LED will blink if the engine speed exceeds 100 km / hour.
