15pcs Capacitive Soil Moisture Sensor Module Soil Sensor

This analog capacitive soil moisture sensor measures soil moisture levels by capacitive sensing, rather than resistive sensing like other types of moisture sensorIt is made of a corrosion resistant material giving it a long service lifeInsert it into soil and impress your friends with the real-time soil moisture dataThis module includes an on-board voltage regulator which gives it an operating voltage range of 3.3 - 5.5VThis sensor is compatible with for DFRobot 3-pin "Gravity" interface, which can be directly connected to the Gravity I/O expansion shieldApplications:Garden plantsMoisture detectionIntelligent agricultureOperating Voltage: DC 3.3-5.5VOutput Voltage: DC 0-3.0VInterface: PH2.0-3PUsage: Temperature SensorType: Vibration SensorTheory: Resistance SensorOutput: Switching TransducerModel Number: soil moduleMaterial:plasticcolour:blackPackage Contents:15 * ModuleOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
