Smart Electronics Soil Moisture Hygrometer Detection Humidity R Module Moisture Water R For Arduino Development Board

Smart Electronics Soil Moisture Hygrometer Detection Humidity r Module Moisture Water r For Arduino Development Board

Descrtion:

1. This is a summary of the moisture r 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 r make an automatic watering system , so that your garden plants need people to manage . 2. adjustable sensitivity ( shown in blue digital potentiometer adjustment ) 3. Operating Voltage 3.3V-5V 4. Module Dual Output mode , a simple digital output , og output more accurate. 5. with fixed bolt hole for easy installation 6. small board size : 3cm * 1.6cm 7. power indicator ( red ) and the digital switch output indicator ( green ) 8. using LM393 comparator ch , stable VCC external 3.3V-5V GND GND External DO small board digital output interfaces ( 0 and 1 ) AO small board og 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 module , which can be composed of a soil moisture alarm equment ; Small plates AO og output modules can be connected and AD through the AD converter , you can get a more accurate value of soil moisture ; Paage Included: 1pcs x Soil Moisture Hygrometer Detection Humidity r Module
