Soil Moisture Sensor
This is an easy to use digital soil moisture sensor. Just insert the sensor in the soil and it can measure moisture or water level content in it. It gives a digital output of 5V when moisture level is high and 0V when the moisture level is low in the soil.
The sensor includes a potentiometer to set the desired moisture threshold. When the sensor measures more moisture than the set threshold, the digital output goes high and an LED indicates the output. When the moisture in the soil is less than the set threshold, the output remains low. The digital output can be connected to a microcontroller to sense the moisture level. The sensor also outputs an analog output which can be connected to the ADC of a microcontroller to get the exact moisture level in the soil.
This sensor is great for making water gardening projects, water sensing, etc.
