ESP Soil Moisture Sensor

Description

ESP8266 based soil moisture sensor Wi-Fi enabled. Also provide ambient temperature and humidity sensor.

At the sensor's heart is an ESP8266 WiFi microcontroller clocked at 80 MHz and at 3.3V logic. This microcontroller contains a Tensilica chip core as well as a full WiFi stack. You can program the microcontroller using the Arduino IDE for an easy-to-run Internet of Things core. You can use ESP8266 flasher that an upload code at a blistering 115200 baud for fast development time. It also has auto-reset so no noodling with pins and reset button pressings.

The sensor can upload sensor datas to remote server. We provided example code for uploading to thingspeak.

== Hardware ==

* ESP-12F module x 1
* Button x 1
* Programming pinouts
* Red led x 1
* DHT11 temperature & humidity sensor x 1
* Soil moisture sensor x 1
* AA Battery holder x 1
* Measures 35mm x 157mm

The project is modifying of the I2C Moisture Sensor project from Miceuz. Thanks for his source code

Hello, is it possible to set up the sensor with ESPeasy?

Are you sure? yes | no

How well is your capacitive probe working? Are you willing to share the PCB design or even just the probe part?

Are you sure? yes | no

in the commentary sneaked error "not low and high illumination"

Are you sure? yes | no

Good afternoon. Found your project on Google, very interested, but I think the design is wrong. So this device is supposed to be used in places with low light, I propose to use a solar panel and small battery. Indirectly, the current from the solar panel, it is possible to measure the illuminance of daylight and in the greenhouse to control the operation of artificial lighting. In the fall, for a long time, light to report on the pollution of solar panels. Thus, I propose to make this device in the form of a flower on a long stem (sunflower) in which to place the soil moisture sensor in the puck inflorescences have a sandwich top to bottom: the solar panel charges the battery and the sensor of temperature and humidity. Flower petals of translucent plastic material and highlight them with different colors depending on the values of the sensors and their readings, customizable from within the app or on the sensor page ( beautifully, clearly and recycle excess power). Thank you for your attention.

Hi! I guess you are using capacitive moisture probing? Could you provide some schematics and code?
Thanks for sharing!

Are you sure? yes | no

Yes. It's capacitive moisture probing. Please check the link for schematic and code.
