About This

• LM393 Soil Moisture Detect Sensor: Used LM393 Chip and Stabilizes. Operating Voltage: 3.3V to 5V; PCB Size: 32mm x 14mm/ 1.26 inch x 0.55 inch; Equipped with a Fixed Bolt Hole that is Easy to Install
• High Quality: LM393 Soil Moisture Detect Sensor Designed with Nickel Plating On the Surface, the Detection Area is Wide, Which Can Increase the Conductivity and Prevent Contact with the Soil and Extend the Service Life
• Wide Range Humidity Regulation: The Humidity of the Soil is Controlled in Large Areas, and the Threshold of Compatible Can Be Used to Regulate Compatibility with Potential
• How to Adjust: The Blue Potential in the Module is Used to Regulate Soil Humidity. If you Adjust it Clockwise, the Controlled Humidity will Increase and It will be Smaller Against the Clockwise. If the Humidity is Lower than the Set Value, the DO Will Output a High Level, and if the Humidity is Higher than the Set Value, the DO Will Output High Levels and DO is Low
• Application: LM393 Soil Moisture Detect Sensor Can Be Used in the Module Plant Watering Device Equipment Without Managing Your Garden Plant. This Must Have a Tool to Connect the Garden! We Recommend that you Wet the Indoor Plant to Water or Monitor the Soil in the Garden
