Measure exact values for soil moisture with just Raspberry pi [2/3/4], moisture sensor and MCP3008 IC.
Do you know how often to water plants? Or outpoured plants and lost them. To solve this I thought it would be more circumstantial if we can get the value of water content inside the soil in order to make a decision for watering the plants appropriately.
In this project lets try to build a circuit which can measure the water content value of the soil eventually control the flow using Raspberry Pi.
