Gikfun 2PCS TDS Sensor Water Conductivity Meter
The Gikfun TDS sensor module provides a practical, economical entry point for measuring conductivity or total dissolved solids in pool water. It supports a wide voltage range from 3.3V to 5.5V and delivers a 0–2.3V analog signal suitable for common microcontroller platforms. With a measurement range of 0–1000 ppm, it suits mid-to-large pool applications where inline monitoring is useful for controlling chemical dosing. The module includes a water-resistant probe for use in outdoor environments and an AC excitation source that helps minimize probe polarization and drift during long-term deployments. This makes it a suitable option for basic conductivity monitoring in commercial pool retrofits or DIY automation projects that support more sophisticated control loops.
Key features include a stable 3.3–5.5V supply, low current draw, and compatibility with 5V or 3.3V controllers. The sensor’s analog output allows straightforward integration into existing pool management dashboards and automation controllers. It is well-suited for operators who want a reasonable balance between cost, ease of wiring, and monitoring capability. For best results, calibrate the sensor against known conductivity standards and consider installing a protective housing to reduce exposure to chlorine and outdoor weather.

Buying Guide
When selecting a conductivity- or temperature-related sensor for a commercial pool, consider:
- Sensor type: Toroidal conductivity sensors excel in accurate measurement of dissolved solids and salinity, while TDS sensors provide straightforward proxies for water quality. Choose based on the primary management goals (chemical dosing, heater efficiency, or sanitation).
- Electrical compatibility: Verify voltage ranges (3.3–5V, 12V, or higher) and output signals (0–2.5V, 0–5V) to ensure seamless integration with existing controllers and dashboards.
- Environmental durability: Outdoor pool environments require moisture resistance, UV tolerance, and chemical resistance. Look for IP ratings or manufacturer claims about long-term exposure performance.
- Cable length and installation: Long cables reduce the need for multiple junctions but may introduce signal delay; ensure adequate length for optimal sensor placement near the control system or valve stacks.
- Calibration and maintenance: Sensors vary in calibration needs. Favor units with documented calibration procedures and accessible replacement parts to minimize downtime.
- Warranty and support: A substantial warranty (12 months or more) and responsive vendor support help reduce total cost of ownership for busy facilities.
- System compatibility: Check compatibility with your automation platform (Pentair, Hayward/Goldline, EasyTouch, IntelliTouch, SunTouch, Compool) to ensure smooth integration and fewer configuration challenges.
In practice, combining a dependable conductivity sensor with a reliable temperature sensor provides a robust foundation for a comprehensive pool water management strategy. By aligning sensor capabilities with your control system and maintenance workflows, facilities can maintain consistent water quality, optimize chemical dosing, and improve energy efficiency across the pool environment.
