![]() ![]() The digital communication is used and implemented on Arduino Uno microcontroller. In this research will be discussed the use of RCWL 0516 sensor as main module to detect the movement of the object by measuring the microwave wave value that displayed on the user gadget by using Blynk application. Based on the problem, a radio-based doppler radar detection tool was developed using RCWL 0516 module. ![]() Every electronic device always has weakness, such as camera needs the light to capture images, Passive InfraRed (PIR) sensor only has ability for human body temperature detection, Short Message Service (SMS) which its services depend on prepay credit and cellular operator signal range. today almost all systems and security tools are using electronic devices such as computers and microcontrollers. Nowdays, along with the development of electronics and computers, the crime rate increases rapidly. ![]()
