Key benefits Simple installation: plugandplay connection with no soldering or welding required, so you can install and the probe quickly without special tools. Stable, lowdrift measurements: AC excitation minimizes probe polarization, improving measurement accuracy and stability during longterm use. Reliable underwater use: fully waterproof probe design allows continuous immersion for extended monitoring in liquids. Broad system compatibility: runs from 3.3 V to 5.5 V and provides a 0–3.3 V analog output, making it compatible with both 3.3 V and 5 V control systems for direct interfacing. Features and technical highlights Installation: easytoconnect, plugandplay interface—no welding required. Excitation method: AC excitation to effectively reduce probe polarization and improve signal reliability. Waterproofing: probe can be immersed in water for longterm measurement without compromising performance. Power and output: Operating voltage: 3.3 V to 5.5 V (wide voltage range for flexible power choices). Analog output: 0–3.3 V analog signal compatible with both 3.3 V and 5 V control systems. Compatibility and integration Directly interfaces with microcontrollers and dataacquisition systems that accept 0–3.3 V analog inputs and run on 3.3 V or 5 V logic. Can be used with common development platforms and embedded controllers (3.3 V and 5 V systems) without additional level shifting or complex wiring. Nosolder connection reduces installation time and risk of wiring errors. Practical applications (examples) Continuous water monitoring: longterm immersion in tanks, reservoirs, or process vessels for consistent, lowmaintenance measurements. Embedded control and datalogging systems: connect directly to microcontrollers and singleboard computers for realtime monitoring, logging, or closedloop control. Field or laboratory testing: portable or bench setups where fast connection, stable readings, and waterproof operation are required. What this solves Eliminates the need for specialized wiring or soldering, reducing installation time and maintenance complexity. Reduces measurement drift and false readings caused by probe polarization thanks to AC excitation. Enables reliable longterm submersion measurements without frequent replacement or recalibration due to the waterproof probe design. Simplifies integration with a wide range of control systems through its broad supply range and 0–3.3 V analog output. Notes for users Ensure your dataacquisition or controller accepts a 0–3.3 V analog input for direct reading. Supply voltage may be chosen anywhere between 3.3 V and 5.5 V based on your system; output remains 0–3.3 V for compatibility with both 3.3 V and 5 V logic environments.
