Soil moisture sensor


Gardening requires lot of time and efforts. One of the main concerns that a person who is interested in maintaining a Garden is, watering the plants and making sure that they get sufficient amount of water. If the soil moisture is less, then plants will die out. And if the moisture is more then also the plants get affected. Thankfully due to developments in the field of electronics, especially in sensors we have a solution for this problem. Graylogix offers Soil Moisture sensor . This sensor is ideal for monitoring soil moisture. This is a must have tool for a connected garden. This sensor uses the two probes to pass current through the soil. If the water content is more in the soil the resistance would be less. If the soil is dry then the resistance to the flow of current would be more. This sensor can easily be connected to a micro controller. You can also connect it to an IoT device so that you can monitor the health of your plants from anywhere in the world. This sensor is ideal for customized projects, academic projects or DIY projects.
