HYDROMATE – Hydroponic Sensor

Description

How It Solves the Problem

 Continuous monitoring avoids delays: The system continuously (or at frequent

intervals) reads key parameters, so changes (e.g. pH drift, nutrient deficiency) can be

detected early.

 Automatic alerts & control reduces human error: When a value goes out of range, the

system can alert the farmer or even do corrective action (e.g. pump in buffer to adjust pH,

add nutrients).

 Lower labour: Once set up, less manual checking is needed. This saves time and cost.

 Better yields / reduced losses: Stable environmental and nutrient conditions mean

healthier plants, less disease, more consistent output.

 Accessibility: By making the hardware affordable and using commonly available parts

(e.g. low-cost sensors, open-source microcontrollers), you can allow small / medium

scale growers to adopt.

 Remote & scalable: With IoT, multiple farms or larger facilities can be monitored from

anywhere. Useful in places where manpower is limited or distances are large.

Why It Is the Best Alternative

Compared to existing solutions, this proposed system could have advantages:

1. Continuous, Real-Time Monitoring

Unlike manual testing (which is done occasionally), this system provides continuous monitoring

of key hydroponic parameters: pH, EC (nutrient concentration), water temperature, humidity, etc.

2. IoT-Based Remote Access

The sensor system connects to a cloud platform or mobile app, allowing growers to monitor their

setup remotely — from a smartphone or computer.

3. Smart Alerts and Automation

Sends real-time alerts (SMS, app notification, email) when parameters go out of range.

4. Open & Modular Architecture

Easily customizable for different plant types or climates.

5. Easy Maintenance & Calibration

Uses replaceable probes and modular design, allowing easy maintenance.

Calibration procedures are simplified and guided via app or dashboard.
