Abstract: Locker is a place that people usually use to keep things. Commonly, lockers are found in campus hall, tourist site, or other public places. Lockers that we face in a daily activities usually still using a conventional keys that we can’t guarantee the security of it. The focus of this research is on online locker rental system that can be accessed through android smartphone and My Locker application by scanning the QR code. Within this system, occurred website that can be used to see the filled locker or the unfilled locker and there’s admin page, to see the summary of data user and the agreement of top up request. The devices component that we used are Node MCU, Relay, solenoid door lock and magnetic door switch. From the result of the test that done by system worked so well and delayed that we achieved while we did the QR code reading experiment with of lux, gap, and gradient slope with optimal condition is 1.45 seconds.
