Home Automation with Raspberry Pi, Programmable Logic Controller (PLC), Android and Wireless




My home automation with raspberry pi for lamp control in the room and outdoor my home. Automation control, especially to lamp control using android phone via wireless. Wireless on android phone connect to router wireless. The router must have a LAN (RJ45) and Wireless. LAN on router connect to raspberry pi via RJ45 cable. And for communication between raspberry pi and PLC using RS232. The function of PLC to turn on or turn off the lamp in my home.
This video about my home automation for lamp control in my room with raspberry pi, PLC and android phone.
