 So, I live on well water. My house is hooked to a pump that's in the ground over there that goes as a tank, and there's another pump inside that tank that fills up the bladder valve over here, which pressurizes to the house. And a few months ago, I had an issue where actually one of the bladder valves went, which caused the pump in the ground to keep on going until it broke, and those pumps are expensive. To get it replaced, it cost me close to a thousand dollars. So, I came up with an idea to set up alarms on it using an ESP8266, which is a little microcontroller about this big, cost about three dollars that hooks to my Wi-Fi. I've actually hooked two of them up, one to the pump in the ground and one to the pump in the tank here, and every time they turn on, the ESP comes on, the ESP8266 hooks to my Wi-Fi and logs that it turned on. And if the ESP8266 stays on for more than five minutes, it starts sending the alerts to my phone because the pump should not be running that long. Now, go to my second channel. I go into this a little more in depth. Go ahead and be sure to check out there. You can be one of the first, because I am sure, I am sure there's going to be comments about how I hooked this up to the high voltage from the house and how I used a Ziploc bag as a weatherproof enclosure for one of them and some Tupperware for the enclosure on the other. So, if you want, you could be one of the first people to criticize me. Go there now! Do it! Link in the description or at the end of this video. Head over there. I've got a lot of videos on hardware on my second channel. This is just one. Thanks for watching. I hope that you have a great day. Please visit FilmsByChris.com. That's Chris of the Cays.
