This paper aims to create hydroponic nutrient mixing system automatically for circulation hydroponic system like NFT (Nutrient Film Technique) and for non-circulation hydroponic system such as drip irrigation system. System continuously sense nutrient concentration and pH level with EC (Electrical Conductivity) sensor and pH sensor. This data will process by ESP32 Wi-Fi microcontroller for monitoring and control dosing pump to maintain nutrient solution EC and pH with the predefined target. In non-circulated hydroponic, nutrition and water will flow into the irrigation system, to control humidity level in plant media, system use soil moisture level sensor. System use IoT cloud Blynk for easy user control and monitoring, user can use application in their smartphone. Test result shows system can increase the EC value from current condition 0.7 to target 3 within ±9 minutes and can maintain the EC value.
