\"ESP-12-04[1]\"<\/a><\/p>\n

This is my second project with ESP8266. I couldn’t find much of info or help regarding in majority of ESP8266 forums. My target is to build a automated irrigation system based on soil moisture sensor data, start the drop irrigation and based on temperature and humidity, starting the mister.<\/p>\n

In this blog, I am going to describe how to connect ESP12F with Soil Moisture sensor(YL-69) and publish the soil moisture data to www.thingspeak.com channel.<\/p>\n

Requirement<\/h2>\n
    \n
  1. ESP-12<\/li>\n
  2. YL-69 Soil moisture sensor<\/li>\n
  3. 12v Power supply (This is needed for my future work, not mandatory for this project)<\/li>\n
  4. 3.3v & 5v Bread board power supply.<\/li>\n
  5. 1K resistor – 2 numbers.<\/li>\n
  6. 8M2 resistor<\/li>\n
  7. Wires needed.<\/li>\n<\/ol>\n

    Lets start:<\/h2>\n

    First connect ESP-12F to UART USB interface for pushing the program. For this ESP need to be in programming mode, connect GPIO0 and Ground after which reboot\/reset the board. Once ESP-12 is powered on with in 30 seconds\u00a0flashing should be started.<\/p>\n
