Control and Monitoring System Design Tunnel Light Using NodeMCU and Arduino Nano and Networking

Transportation serves as a means of connecting and has a very significant role in the movement of goods and people. Road transportation as connectivity between regions in urban areas, has tunnel roads that serve car and motorcycle riders for 24 hours. For this reason, it is necessary to control and monitor tunnel lights so that the quality of street lighting is well maintained in accordance with the specified lighting standar value. The purpose of this research is to design a tunnel light control and monitoring system using NodeMCU and Arduino Nano that can be controlled remotely using WiFi networking solution. This monitoring system is equipped with an Arduino Nano controller electronic circuit, RS485, INA219 current sensor and LM393 light sensor. From the test results, it was found that the system was able to control 8 tunnel LED lights, 4 on the left side and 4 on the right side of the tunnel road. The monitoring results show that the tunnel lights can be controlled by dimmer value of 6 and 12 on the flame and dim and the current value and lumens value of each light point can be monitored.
