“My basement gets wet when it rains a lot so I wanted a way to monitor it. I decided to try using an ESP8266 as it has built in WiFi. I paired that with a DHT22 Humidity & Temperature Sensor and a float sensor to monitor my sump pump. Using the ESP8266 is easy enough as you can just use the Arduino IDE to program it. Besides the parts below you will need access to WiFi Dweet.io and Freeboard.io. These two web services make it easy to create a dashboard with your data.”
