1.Soil PH Sensor Product Introduction
Soil PH Sensor measures the pH value of the soil and indicates whether the soil is acidic, neutral or alkaline. It can be inserted directly into the soil to obtain an accurate pH reading.Soil PH Sensor measures the pH value of the soil and indicates whether the soil is acidic, neutral or alkaline. It can be inserted directly into the soil to obtain an accurate pH reading.The soil pH sensor solves the shortcomings of traditional soil pH sensors, such as the need for professional display instruments, cumbersome calibration, high integration difficulty, high power consumption, high price, and difficulty in carrying. It can be widely used in agricultural irrigation, flower gardening, grassland pasture, soil rapid testing, plant cultivation, scientific experiments and other fields. It has low power consumption and can perform long-term uninterrupted monitoring. The sensor has the following characteristics:
The new soil pH sensor realizes online real-time monitoring of soil pH.
It uses solid dielectric and large area PTFE liquid junction, which is not easy to be blocked and maintenance-free.
Waterproof and sealed, high integration, small size, low power consumption, easy to carry, and can be used outdoors.
High precision, fast response, good interchangeability and reliable performance.
Complete protection circuit and multiple signal output interfaces are optional.

The configuration parameters of the sensor, such as Modbus address, baud rate, check bit, communication protocol, etc., are stored in the EEPROM (power-off storage device) inside the module. Sometimes the specific configuration of these parameters is forgotten, resulting in failure to communicate with the module. In order to prevent this problem, the module has a button. After pressing it for three seconds, the indicator light inside the module goes out. Release the button and all the parameters of the module will be restored to the following factory settings: 1. Modbus address is 1 2. The communication configuration is 9600,N,8,1 (9600bps, no parity bit, 8 data bits, 1 stop bit) The communication protocol is Modbus-RTU |
