Common problems with the use of ph sensors In practical use, pH in practical use, the following problems may exist in pH sensors: reduced sensitivity/slope, sluggish response, noise signals and chemical damage.

calibration of the PH sensor has a certain periodicity, and the calibration cycle is different according to different use conditions. Generally, it can be calibrated once every four to eight weeks.

Precautions for rain sensor use:1. The length of the sensor line will affect the output signal of the product. Do not arbitrarily change the components or wires that have been soldered when the product leaves the factory;

Small weather stations should be assigned a person to manage and regularly check the weather station, and also to prevent pests, because the sensors of the weather station are processed and collected on the collector and displayed on the computer, if the rats chew the cable, it is not only inconvenient to repair, but also the data of the sensors on the weather station can not be accurately transmi···

For agricultural weather stations, sensors are very important and have high accuracy and reliability. The weather station equipment is generally used continuously year after year, in daily use, how should the agricultural weather station maintenance and maintenance?

it is necessary to strengthen the training of managers' skills related to the use of agricultural environment, and to identify the instruments in time to improve the efficiency of the use of agricultural weather stations.

Meteorological station rain gauge data abnormal causes.Residual rainwater: The equipment commonly used for precipitation data monitoring is the tipping bucket rain gauge. The tipping bucket is the part of the rain gauge that collects rainwater, but if there is a part of residual rainwater in the tipping bucket, it will make the precipitation data have a small deviation.

Reasons for abnormal data: Wind speed data problems are generally the cause of the poly-carbon wind speed sensor, poly-carbon wind speed sensor using mechanical structure design, there are rotating parts, so there is a minimum wind speed before monitoring as a start condition, if the wind speed is lower than the start value will not be able to drive the propeller or wind cup for rotation, it will ···

How to install the soil sensor:Quick measurement method:(1) Choose a suitable measurement location and avoid clods;(2) According to the measured depth, plan the topsoil;

Soil moisture sensor operation precautions:1. Before the measurement, the soil with uniform density should be selected as the measured object;2. Do not insert the sensor probe into the hard soil block to prevent the probe from being damaged;
