DIY Moisture-Based Smart Irrigation

We know that plants require water as it acts as a transportation medium for nutrients by carrying the dissolved sugar and other nutrients through the plant. Without water, plants will wither. However excessive watering will fill pores in the soil, disturbing the balance of water and air and preventing the plant from breathing. Proper balance of water is important. The soil moisture sensor measures the moisture content of the soil. By deciding on a particular percentage, we can be reminded to water our plants when the soil is too dry.
However, we do not measure the amount of water flow each time we water them and often we are either watering them too much or too little. To properly water them, we can use a flow sensor to measure the flow of water and a relay to stop the flow after a particular amount of water has been supplied.”
