Soil pH sensor

[Product Description] ■ IoT soil pH sensor featuring both RS-485 and Wi-Fi web interfaces for remote or on-site mobile monitoring, no display or app required. ■ Smart calibration function: The protective cover can be directly replaced with a standard liquid bottle, and the mobile web interface provides a guided calibration process, making on-site calibration extremely easy, with remote calibration also available. ■ Smart AI features: Calibration/self-cleaning status notifications. [Features] ■ Integrated design with built-in IoT transmission and sensor; simply power on to operate—all functions are pre-installed. ■ Ultra-low power consumption, suitable for green energy IoT deployments. ■ High-strength insulated cable for direct use, ensuring stable signals. ■ Includes temperature compensation and measurement methods compliant with the EPA's automatic monitoring facilities regulations NIEA W218.51C. ■ Power and IoT signals have surge isolation protection. ■ Dual digital communication via RS-485 and Wi-Fi. ■ Standard Modbus RTU protocol for global IoT connectivity. ■ Smart design allows for saving calibration parameters; calibrated devices can be directly installed on-site. ■ Mobile web operation for convenient on-site use. ■ On-site protective cover can be replaced with a standard liquid bottle for easy calibration. ■ Features three-point calibration, allowing calibration with standard solutions or known concentration samples. ■ During calibration and self-cleaning, it retains the last read value to avoid false triggers, while displaying status (calibrating/self-cleaning/stabilizing/maintenance). ■ Latest three calibration records (date/slope/calibration points) can be queried via Web and RS-485. [Applicable Locations] Ideal for soil and various applications requiring insertion-type pH measurement.
