The Soil pH Sensor is an NB-IoT pH sensor that utilizes an RS485 interface and a standard transparent transmission protocol, enabling simultaneous multi-point monitoring, networking, and remote transmission. It is suitable for various environments, particularly for soil and wastewater treatment applications. To facilitate engineering networking and industrial applications, this module adopts the widely used NB-IoT communication protocol and supports secondary development.

Product Introduction

The Soil pH Sensor employs NB-IoT/LoRa/LoRaWAN standard transparent transmission protocols, allowing simultaneous multi-point monitoring, networking, and remote transmission. It is suitable for various environments, especially for soil and wastewater treatment applications. To facilitate engineering networking, the soil pH sensor effectively addresses the shortcomings of traditional soil pH measurement methods, such as the need for specialized display instruments, cumbersome calibration, difficult integration of wiring methods, high power consumption, high cost, and portability issues. It is an intelligent upgrade to industrial pH meters, capable of continuous measurement and control of soil and wastewater pH. This device is also applicable in urban wastewater treatment plants, chemical, printing and dyeing, papermaking, pharmaceutical, electroplating, and environmental protection industries.
