ESP8266 Community Forum

Here you can see an IoT soil moisture sensor built around the ESP8266 SoC and a soil moisture sensor with an analog output. To visualize the data at browser side I have used chart.js which is easy to handle and looks rad! Furthermore, I decided to dynamically change the value of CSS filter according to the data received, in order to reflect the plant’s drainage. To enhance user experience I have also developed an android app, where I've used MPandroidChart.
