NIFPES_Speech_IOT_Project

NIFPES_Speech_IOT_Project thumbnail
This is a speech output model for a NIFPES (Nitrogen Injection Fire Prevention and Exhaustion System) machine. ESP32 is being used where it is connected with a limit switch LXW20-11M and ESP32 is connected with DFPlayer mini MP3 Speaker module and the speaker module is further connected to a speaker. This model is powered by a PLC SMPS of 24V and is connected to the door of the control panel of the machine.
Function:- Now whenever the door is opened or closed, there is a speech output from the speaker "The door is open" or "The door is closed".
Further work to be done:- I need to integrate the fire alarm signals and 20 more signals of 24v each from the PLC output to the ESP32 so that there can be speech outputs whenever any signal is high.
