New 3.3-5.5V for Capacitive Soil Moisture Sensor Module Dry Moisture Detection for for

New 3.3-5.5V for Capacitive Soil Moisture Sensor Module Dry Moisture Detection for for The new soil moisture sensor is finally released! This capacitive soil moisture sensor is different from most resistive sensors on the market. It uses the capacitive sensing principle to detect soil moisture. It avoids the problem of easy of resistive sensors and greatly extends their service life. The sensor has a built-in voltage regulator chip and supports a wide voltage range of 3.3-5.5V, which can work properly even on a 3.3V for control board. The iconic for interface ensures compatibility and can be directly connected to the Gavity IO expansion board. Mini PCs like for only need an external ADC (analog-to-digital conversion) module to work. Connect an external screen and an for mainboard, and you can talk to your plants! See if your beloved plants are thirsty and need . Color: Black Material: ABS Package Contents: 1 set x Soil moisture sensor module Only the above package content, other products are not included.
