Soil moisture sensor M413
This is a simple water sensor, can be used to detect soil moisture. Module output is high level when the soil moisture deficit or output is low. It can be used in module plant watering device and the plants in your garden no need people to manage. 2 Adjustable sensitivity by adjusting the digital potentiometer. Dual output mode that is digital and analog both. Analog interfacing can be used for accurate output. Has an east to insert soil probe that can be placed in the soil to be monitored. With power indicator (red) and digital switching output indicator (green). Having lm393 comparator chip, stable the soil moisture sensor can be easily interfaced to any microcontroller to its digital pin if the required output is digital like to put on and off the water pump depending on the water content. It can be interfaced via an adc to the microcontroller for multi level monitoring like if the flow of water is also to be controlLED.
