HQ Soil Moisture Hygrometer Detection Humidity Sensor Module

Detail HQ Soil Moisture Hygrometer Detection Humidity Sensor Module

hai kak. Mohon maaf untuk minimal order 20 ribu ya kak baru bisa kita proses, diluar ongkirSTOCK per 15 jan = 50 pcs

1 This is a summary of the moisture sensor can be used to detect the moisture of
the soil, when the soil is dry , the module outputs a high level , whereas the
output low. Using this sensor make an automatic watering system , so that your
garden plants need people to manage .

2 adjustable sensitivity ( shown in blue digital potentiometer adjustment )

4 Operating Voltage 3.3V-5V

5 Module Dual Output mode , a simple digital output , analog output more
accurate.

6 with fixed bolt hole for easy installation

7 small PCB board size : 3cm * 1.6cm

8 power indicator ( red ) and the digital switch output indicator ( green )

9 using LM393 comparator chip , stable

VCC external 3.3V-5V
GND GND External
DO small board digital output interfaces ( 0 and 1 )
AO small board analog output interface

Instructions

A soil moisture and humidity module most sensitive to the environment , usually
used to detect soil moisture .
Modules in the soil moisture reach the set threshold , DO port output high when
soil moisture exceeds a set threshold, the module D0 output low ;
Digital outputs D0 small plates can be directly connected with the
microcontroller through the microcontroller to detect high and low , thereby
detecting soil moisture ;
Small plates digital output DO OUR relay module can directly drive the buzzer
module , which can be composed of a soil moisture alarm equipment ;
Small plates AO analog output modules can be connected and AD through the AD
converter , you can get a more accurate value of soil moisture ;

Package Included:

1pcs X Soli moisture sensors
