Introducing soil and ground resistivity hygrometer module SR1 Model
You can use the soil and ground moisture meter module to measure the soil moisture level and determine if the soil has enough moisture or not, or what the soil hardness is. This module has an electronic part and a prop part, where the props are placed inside the soil and connected to the electronic circuit by a wire. In this way, the electronic circuit can read and measure the moisture level of the soil using props. In the picture below, you can see how this moisture sensor is placed inside the soil.
Applications of soil moisture meter module
This module is used to measure the moisture level of the soil, which you can use to intelligently water the plants. The construction of an automatic irrigation system for gardens – greenhouses and house and apartment plants is one of the main applications of this sensor. The hygrometer module has two pins to connect the props and four pins to connect with the circuit, out of these four pins, two are the power supply of the module, and the other two are the digital signal output, which is either zero or one. It also has an analog signal output.
You can use one of these signal output pins as needed. Also, this module has the ability to communicate with all kinds of micro-controllers and boards such as Arduino, which you can easily build a smart irrigation system. You can see the connections of this sensor in the picture below.
First of all, we suggest you watch the following tutorial video to learn more about this sensor
As shown in the picture, this sensor has two sockets, which are the power socket and signal output socket shown here.
The mentioned sensor is one of the most accurate and widely used soil and ground moisture meter sensors that you can easily use to automate plant watering.
Keep in mind that this module is only a sensor that reads and measures the soil moisture and does not perform the irrigation work on its own. Therefore, you must connect this sensor to the plant watering devices so that the device can use the moisture meter sensor. Measure the condition and moisture content of the soil.
