The ESP32 is a versatile microcontroller that can be used to interface with pH sensor,TDS sensor,pump,floating switch and communication modules in hydrogrowpro.

• Connect sensors to the ESP32 to monitor crucial parameters such as pH value and TDS value
• Interface the ESP32 with water pumps
• Implement communication protocols like MQTT or HTTP to enable the ESP32 to send data to a central server or receive commands.

pH sensor is a device used to measure the acidity of solution. In the context of an automated hydroponic system, the pH sensor is crucial for monitoring and controlling the pH level of the nutrient solution.Here how we uaed it :

• Install the pH sensor in the nutrient solution reservoir. Ensure that it is properly submerged and free from air bubbles.
• Connect the sensor to the microcontroller
• The pH sensor continuously measures the pH level of the nutrient solution.

A TDS (Total Dissolved Solids) sensor is an essential component in our automated hydroponic system for monitoring the concentration of dissolved minerals and salts in the nutrient solution. Here's how it works :

• Install the TDS sensor in the nutrient solution reservoir .Ensure proper submersion and absence of air bubbles for accurate readings.
• Connect the sensor to the microcontroller
• The TDS sensor continuously measures the electrical conductivity of the nutrient solution.
• Readings are transmitted to the microcontroller, providing real-time information about the TDS level.

In an automated hydroponic system, the floating switch can be used for controlling and monitoring the water level in reservoir. Here's how a floating switch could be implemented:

• When the nutrient solution level changes, the float moves up or down accordingly.
• The movement of the float triggers the switch mechanism.
• When the nutrient solution level drops below a certain point, the floating switch activates a pump to refill the reservoir.
