Hw-390 Capacitive Soil Moisture Sensor Not Easy To Corrode Wide Voltage Operation Wire Feeding Black
Features:1. New soil moisture sensor: The principle of capacitive sensing is used to detect soil moisture. The problem that the resistive sensor is easily corroded is avoided, which greatly prolongs its working life.2. The built-in voltage regulator chip supports 3.3~5.5V wide voltage working environment, which means it can work normally even on the 3.3V Arduino main control board. A miniature PC such as the Raspberry Pi only needs an external ADC (analog signal to digital signal) conversion module to work.3. An external screen, a motherboard, you can talk to your plant! Look at the beloved, is it thirsty, need not need a little more water to moisturize.Description:The principle of capacitive sensing is used to detect soil moisture. The problem that the resistive sensor is easily corroded is avoided, which greatly prolongs its working life.Specifications:Operating voltage: Output voltage: 0 ~ 3.0 VDCInterface: PH2.0-3PPackage Included:1 * Soil moisture sensorNotes:1. Due to differences between different displays, the picture may not reflect the actual color of the item.2. Physical errors may exist due to different personal measurement techniques. Thank you! ![]()
