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.
