Liquid PH Regulator/Controller Board

Integrated Signal Conditioning Circuitry: Converts micro-volt analog outputs from glass pH electrodes into calibrated, low-noise analog voltage signals suitable for microcontroller ADCs.

Onboard Potentiometer Trimmers: Features dual high-precision multi-turn potentiometers to adjust gain offset and set digital alert switching thresholds.

Standard BNC Probe Interface: Outfitted with a heavy-duty female BNC connector for seamless compatibility with standard laboratory and industrial glass pH electrode probes.

Dual Signal Output Modes: Provides continuous analog voltage output (Po) for real-time tracking alongside a digital switching output (Do) for automated threshold alerts.

Visual LED Status Telemetry: Equipped with onboard power and signal output LEDs to deliver quick visual indication during circuit testing and setup calibration.

Board Material: High-grade FR-4 glass-epoxy PCB with corrosion-resistant tinned solder pads and plated BNC socket hardware.

Technical Specifications:

Input Supply Voltage: 5.0V ± 0.2V DC.

Measurement Spectrum: 0.00 - 14.00 pH.

Operating Temperature: 0°C - 60°C.

Output Signals: Analog Voltage Output (Po) + Digital Logic Switching (Do).

Response Time: ≤ 5s (pH acquisition stability).

Board Color: Green PCB with Blue Potentiometers & Metallic BNC Connector.

Usage Advice: Wire 5V, GND, and Po to your microcontroller's analog pin; attach a BNC glass pH probe, and calibrate using standard buffer solutions prior to system deployment.

Maintenance: Keep the circuit board free from direct water contact or chemical splash; clean connection pins with isopropyl alcohol if oxidation occurs.

Essential Closed-Loop Water Dosing Hub: Position as an indispensable interface board for automated hydroponics, aquaponics, swimming pool chemical dosing, and industrial fluid control setups.

Highlight Plug-and-Play BNC Standard: Emphasize how the standard BNC interface allows easy swapping or upgrading of pH electrodes without replacing the control driver board.

Recommended Cross-Sell Add-ons: Pair with 0-14pH Electrode Probe Sensor BNC Connector, Standard pH4.01 + pH6.86 + PH9.18 Calibration Powder, DFRobot Gravity Analog TDS Sensor module, and ESD antistatic mat 50x40CM PCB Welding Mat.
