Description

The Grove ORP Sensor Kit provides a direct method to measure the oxidative or reductive capacity of a solution, critical for assessing water quality in environmental monitoring, aquaculture, and hydroponics. The sensor outputs a millivolt-level signal proportional to the ORP, which is conditioned by the onboard driver circuit for reliable reading by microcontrollers.

Designed for robustness, the probe and electronics operate within a 5°C to 70°C range, suitable for most field and lab conditions. The kit’s modular Grove system eliminates complex wiring, making it an optimal choice for rapid prototyping and educational projects focused on chemical sensing and data logging.

Key Features

  • Integrated BNC connector for secure, standard probe attachment.
  • Grove 4-pin interface simplifies connection to base shields and microcontrollers.
  • Low reference electrode internal resistance (≤10kΩ) ensures stable signal acquisition.
  • Compact driver board footprint for easy integration into portable monitoring setups.
  • Wide operating temperature range supports both indoor and outdoor applications.

Applications

  • Aquaculture and hydroponic system water quality monitoring.
  • Environmental field studies measuring redox potential in lakes and rivers.
  • Swimming pool and spa water sanitization level (chlorine activity) sensing.
  • Educational lab setups for chemistry and environmental science projects.
  • Wastewater treatment process control and effluent monitoring.

Frequently Asked Questions

What is the operating voltage range for this Grove ORP Sensor?

The sensor driver board operates from a 3.3V to 5V DC power supply, making it directly compatible with most Arduino boards, Raspberry Pi GPIO (using appropriate logic level shifting for 3.3V Pi models), and other 5V or 3.3V microcontroller systems without requiring an external voltage regulator.

How do I interface the ORP probe with the driver board?

The included ORP probe connects via a standard BNC connector on the driver board. The sensor's analog output signal is then accessible through the 4-pin Grove connector, which carries VCC, GND, and the signal line. Use the provided Grove cable to link the board to a Grove-compatible base shield or breakout.

What does the electrode stability specification (±8mV/24hr) mean?

This specification indicates the maximum expected drift of the sensor's millivolt output over a 24-hour period under stable conditions. A stability of ±8mV ensures consistent readings for medium-precision monitoring applications, though periodic calibration against a standard ORP solution is recommended for critical measurements.
