Looking for **cheap ** solution, battery powered- sensor/chip/board, that can send an e-mail when tripped on local Wi-Fi. No other functions necessary. Pi or Arduino way over kill.
I am looking for a solution a single chip or sensor, or the like, that when tripped (two metal plates completing a circuit), a single e-mail will be sent over the local WiFi network. No other functions are needed. It should be battery powered (portable). A Pi or Arduino like device is way over kill.. I'm looking for something very small, and cheap. Like sub $20, or less. Its a DIY prototype for an animal trap.. I simply want to receive an alert when the trap is tripped. Im a little new to the topic, and finding resources and products is more difficult than expected. I envision a small board, with a battery, when the trap trips, it acts like a power on button, the device powers up, send a message/signal/or whatever, then shuts down again. Or could send a message every hour. Its obviously just something I want to play around with, but will use it to develop my skills to more advanced stuff
