The sensor to determine the moisture level of the soil. It is powered with the voltage from 3.1 V to 5 V. The output is the analog voltage which increases its value along with the increasing moisture content which makes it compatible with most commissioning modules, for example, Arduino. The device can be used, for example, for measuring the moisture content of the soil in the pot.

The sensor has an analog output that should be connected to the pin of the A/D converter (analog input in Arduino). This will allow you to measure the proportional voltage signal and at the same time to determine the level of soil moisture.

Operating principle:
This module is an application of the current amplification by a transistor. When the water in the soil is sufficient enough to conduct the current between the base and the positive power supply, a certain amount of current is generated between the base and the emitter. And in a mean while, an electric current is produced in a certain amplification factor between the collector and the emitter, and applied to the resistant in the emitter to produce a voltage. Then, this voltage will be collected by an AD converter.

These Humidity Sensors can be used to detect the environmental relative humidity. Used in many end products such as air conditioners, humidifiers, dehumidifiers, hygrometers, recorders, and transmitters. A humidity Sensor is an instrument used for measuring the moisture content in the environmental air or powders. Most measurement devices usually rely on measurements of some other quantity such as temperature, pressure, mass, or a mechanical or electrical change in a substance as moisture is absorbed.

From calculations based on physical principles, or especially by calibration with a reference standard, these measured quantities can lead to a measurement of humidity. Modern electronic devices use temperature of condensation, or changes in electrical capacitance or resistance to measure humidity changes.
