Using a Moisture sensor module with a microcontroller is very easy. The internal Circuit diagram of the Moisture sensor module is given below. Digital out pin is connected to the output pin of LM393 comparator IC while the analog pin is connected to Moisture sensor. Moisture sensor module consists of four pins i.e. Using the onboard preset you can adjust the threshold (sensitivity) of the digital output. These two probes are used to pass the current through the soil and then the sensor reads the resistance to get the moisture values. The moisture sensor probes are coated with immersion gold that protects Nickel from oxidation. The moisture sensor consists of two probes that are used to detect the moisture of the soil. The comparator IC will compare the threshold voltage set using the preset (pin2) and the sensor pin (pin3). Pin 2 of LM393 is connected to Preset (10KΩ Pot) while pin 3 is connected to Moisture sensor pin. LM393 Comparator IC is used as a voltage comparator in this Moisture sensor module. This Moisture sensor module consists of a Moisture sensor, Resistors, Capacitor, Potentiometer, Comparator LM393 IC, Power and Status LED in an integrated circuit. Easy to use with Microcontrollers or even with normal Digital/Analog IC.Output Analog - 0V to 5V based on infrared radiation from fire flame falling on the sensor.Output Digital - 0V to 5V, Adjustable trigger level from preset.Soil Moisture Sensor Module Features & Specifications The module has both digital and analog outputs and a potentiometer to adjust the threshold level.Ī waterproof sensor probe with high corrosion resistance ensures a lifetime of at least 6 months in the soil. It measures the volumetric content of water inside the soil and gives us the moisture level as output.

It is required you have a free account in order to complete this task.This soil moisture sensor module is used to detect the moisture of the soil. In order to achieve it, we configure a short message service in IFTTT. As stated before, we want to send a short message when the humidity hits a threshold level. Before completing the work on Carriots, it is useful to configure the IFTTT. The interesting aspect of Carriots is that we can use Groovy as a scripting language to invoke external services. When the rule is verified then it invokes a script. A listener is a process that analyzes the incoming values and applies a specific rule. In order to alert the user we need two components:Īs a monitoring data system, this IoT system uses Carriots listener.

Internet of Things with Android and Arduino: Control remote Led Running the sketch, we can notice that the device sends data to the Carriots as shown below: This function must be invoked in the loop() method. Notice that the function sends a JSON payload containing the data read from the sensor.

Serial.println( "Connected to the server.") The picture below shows how to connect the YL-38 and YL69 (moisture sensor) to Arduino: This is an analog sensor that can be inserted into the soil we want to monitor.
This IoT project uses YL-38 + YL-69 sensor. In this first step, we have to read the sensor data. Retrieving data from the soil moisture sensor connected to Arduino Moreover, this project displays the humidity soil status using a LEDs matrix. Building this IoT system we can explore how to use several components of the IoT ecosystem.
By now, we can assume that the Carriots IoT platform is able somehow to invoke an IFTTT service that will send a short message to the user alerting him. We will see later how to analyze the data. This platform, in turn, stores the data coming from the sensor and detects when the values stored are under a threshold level. The Arduino MKR1000 controls the sensor sending the data to the Carriots IoT platform (now Altair SmartCore). The idea that stands behind this project is building an Arduino IoT system that monitors the soil moisture using a soil sensor detecting when it gets too dry.
