Vibration sensor using ESP8266 and NodeMCU
Posted: Thu Apr 16, 2015 6:32 pmA simple vibration sensor can be connected to the ESP8266 GPIO pin and an alarm can be triggered via TCP to report vibration. This could be useful for a number of things, including industrial monitoring, security, etc. The prototype uses a sensor originally designed for Arduino, but can easily be connected to one of the GPIOs in the ESP8266. SSID and password for the WIFI can be programmed remotely via web as with my other prototypes and the nice things is that the server address and the port number the server is listening at can also be programmed remotely via web, no serial connection required and it is persistent!!!
