If the moisture content of the soil is optimum for plant growth, plants can readily absorb soil water. Step 2. // READ THE MOISTURE SENSOR 2 66 int sensorVal3 = analogRead (A2); // READ THE MOISTURE SENSOR 3 67 int sensorVal4 = analogRead (A3) . This library can handle both 4 bit mode and 8 bit mode wiring of LCD. Arduino CODE. Then I tried with my plant. After that, we have set the A0 pin of the sensor as the input by declaring its pinMode() as the INTPUT. 9V battery must go to a step-down regulator first, so you get something like this, battery+[9V] -> regulatorVCC -> VCC[5V] If you prefer not to solder, you can purchase the sensor with a 3-pin screw terminal pre-soldered onto the board. 4) Connect your Arduino Uno to a laptop/PC and burn the code provided below on the arduino. Revision History: As of Jan 7, 2020 - Adafruit have tweaked the firmware to take more oversamples before returning a value. This value is then saved in msvalue tobe later used in the code. 2021 Arduino S.r.l. Just refer to schematics.

Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. This is a must have tool for a connected garden! It is also possible to read the amount of moisture present in the soil (for judging whether the soil is wet or dry) by linking the analog output (AO) of the module, to one analog input (A0) of the Arduino. Multiplying this number by 0.48828125 converts that value to . If we don't have Grove Base Shield, We also can directly connect Grove-Moisture Sensor to Seeeduino as below. Save my name, email, and website in this browser for the next time I comment. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. When the soil humidity is below a set threshold value, D_OUT port outputs high (H), and when the soil humidity exceeds a set threshold value, it outputs low (L). If the value is less than threshold 70, then it will turn on a water pump. Importantly, I used ground (GND) from the 12V switching power supply and connected to the Arduino Uno board. Which displays the soil moisture value in percentage. I cant find the SL100B Transistor, Connect the VCC pin to 3.3V of NodeMCU and GND to GND. The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). Well, you have VCC and GND, so you get your +5V and connect it to VCC, and you get your 0V ( gnd ) and connect it to GND. Instead of a value close to 100 or below 300, it return a value of 700. Let's hook up the soil moisture sensor to the Arduino. ThingSpeak API. Product Dimensions: 76.2mm x 14.0mm x 7.0mm / 3.0" x 0.6" x 0.3". We can easily interface this module with any microcontroller using SPI/IIC protocols. The following project measures soil moisture, humidity, and temperature. The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is wet (determined by a pre-setted threshold value). The soil moisture is monitored in real-time. From this, we can get the maximum and minimum analog value that can be mapped to percentage value from 0 to 100% as per the program.
