Bộ Cảm Biến Độ Ẩm Của Đất Arduino W / Dupont L & 6

Dear, welcome to kidsworld, here are the latest products for you to choose from, we use the original heart, do the best products, 24H Q&A session, answer all your questions, please go down to see the product~

Features:
-This is a simple water sensor can be used to detect soil moisture when the soil moisture deficit module outputs a high level, and vice versa output low. Use this sensor produced an automatic plant waterer device, so that the plants in your garden without people to manage.
-Sensitivity adjustable the blue digital potentiometer adjustment (Figure).
-Module dual output mode, digital output, analog output more accurate.
-With fixed bolt hole for easy installation.
-Power indicator (red) and digital switching output indicator (green).
-Comparator LM393 chip, stable.

Specifications:
-VCC: 3.3 V-5V
-GND: GND
-DO: digital output interface (0 and 1)
-AO: Analog Output Interface
-Operating voltage 3.3V-5V
-PCB Size: approx. 3.2* 1.4cm/1.25*0.55''
-Sensor size: approx. 65*20*8mm/2.55*0.78*0.31''
-Net weight: approx. 8g
-Quantity: 2pcs

Instructions for use:
-Soil moisture module is most sensitive to the ambient humidity is
generally used to detect the moisture content of the soil.
-Module to reach the threshold value is set in the soil moisture, DO port
output high, when the the soil humidity exceeds a set threshold value, the
module D0 output low.
-The digital output D0 can be connected directly with the microcontroller
to detect high and low by the microcontroller to detect soil moisture.
-The digital outputs DO shop relay module can directly drive the buzzer
module, which can form a soil moisture alarm equipment.
-Analog output AO and AD module connected through the AD converter, you
can get more precise values of soil moisture.

Note:
Please allow 1-3mm differs due to manual measurement.
