Description

he FC-28 soil moisture sensor is a useful tool for monitoring the moisture content in the soil. With its reliable and accurate readings, it helps gardeners and farmers determine when and how much to water their plants. This sensor is easy to use and can be connected to a microcontroller or Arduino for data collection and analysis. It operates on a 5V power supply and outputs an analog signal that corresponds to the soil moisture level. The FC-28 sensor consists of two probes that are inserted into the soil, allowing it to measure the resistance and translate it into a moisture reading. This information can then be used to optimize irrigation practices and prevent overwatering, ensuring healthier and more productive plants. A soil moisture sensor can read the amount of moisture present in the soil surrounding it. It's a low tech sensor, but ideal for monitoring an urban garden, or your pet plant's water level. This is a must have tool for a connected garden! This sensor uses the two probes to pass current through the soil, and then it reads that resistance to get the moisture level. More water makes the soil conduct electricity more easily (less resistance), while dry soil conducts electricity poorly (more resistance). It will be helpful to remind you to water your indoor plants or to monitor the soil moisture in your garden. The IO Expansion Shield is the perfect shield to connect this sensor to Arduino. Soil moisture sensor uses Immersion Gold which protects the nickel from oxidation. Electroless nickel immersion gold (ENIG) has several advantages over more conventional (and cheaper) surface platings such as HASL (solder), including excellent surface planarity (particularly helpful for PCB's with large BGA packages), good oxidation resistance, and usability for untreated contact surfaces such as membrane switches and contact points.
