TECNOIOT 5pcs Soil Hygrometer Humidity Detection Module Moisture Water Sensor

【SOILSENSOR】 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 at high level, whereas the output low. Using this sensor make an automatic watering system, so that your garden plants need people to manage. 【Design compact】 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 ; 【Easy operation】 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. 【High performance】 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; 【Entrega rápida】Envío desde España con llegada rápida a toda la UE
