TECNOULAB 2 Pieces Soil Hygrometer Moisture Detection Module Water Humidity Sensor

【SOIL SENSOR】This is a summary of the moisture sensor which can be used to detect soil moisture, when the soil is dry, the module has high performance, while the performance is low. 【Compact Design】A more environmentally sensitive soil moisture and moisture module, generally used to detect soil moisture. Modules in soil moisture reach the set threshold, the output of the OD port is high when the soil moisture exceeds a set threshold, the output of the D0 module is low; 【Simple Operation】The small D0 digital output boards can be directly connected to the microcontroller through the microcontroller to detect high and low, thus detecting soil moisture; 【High Performance】Small board AO and AD analog output modules can be connected through AD converter, you can get more accurate value of soil moisture; Using this sensor creates an automatic watering system, so the plants in your garden need staff to manage them. 【High Performance】Small board digital output Our relay module can directly drive the buzzer module, which can be composed of soil moisture alarm equipment.
