Good Wholesale Vendors Wired Rain Sensor - Three Temperature and Three Humidity Soil Moisture Recorder – Huacheng
Good Wholesale Vendors Wired Rain Sensor - Three Temperature and Three Humidity Soil Moisture Recorder – Huacheng Detail:
1. Introduction
The soil moisture sensor is a high-precision, high-sensitivity sensor that measures soil temperature. Its working principle is that measuring soil moisture through FDR (frequency domain method) can correspond to soil volumetric moisture content, which is a soil moisture measurement method that conforms to current international standards. The transmitter has signal acquisition, zero drift and temperature compensation functions. This sensor is suitable for fields that need to measure soil moisture, such as meteorology, environment, agriculture, forestry, water conservancy, electricity, etc.
2. Features
High measurement accuracy, fast response and good interchangeability
With power reverse connection protection function
Epoxy resin casting, good sealing and corrosion resistance, can be buried in the soil for a long time
Small size design, easy to carry, easy installation, operation and maintenance.
Stainless steel probes guarantee longevity.
Reliable performance, less affected by soil salinity, suitable for various soil types

1. Introduction
The soil temperature sensor is a high-precision, high-sensitivity sensor for measuring soil temperature. Its working principle is to read the temperature value through a high-precision digital temperature chip. The transmitter has signal acquisition, zero drift and temperature compensation functions. This sensor is suitable for fields that need to measure soil temperature, such as meteorology, environment, agriculture, forestry, water conservancy, electricity, etc.
2. Features
High measurement accuracy, fast response and good interchangeability
Easy installation and simple operation
With power reverse connection protection function
Epoxy resin casting, corrosion resistance
3. Technical parameters
⊙Accuracy: ±0.2℃
⊙Measuring range: -40℃~60℃
⊙ Lead length: 2.5 meters (can be customized)
⊙ Circuit sealing: epoxy resin
⊙Stable time: 500ms after power-on
⊙Power consumption: normal 20mA, peak 50mA
★Voltage output type
Supply voltage: 7-24v DC
Output signal: 0.4-2v or 0-2v
Temperature value=(output voltage-0.4)/1.6*100-40 or output voltage/2*100-40
There are two ways to plug in the sensor:
1、Quick measurement method: Select a suitable measurement location, avoid stones, make sure that the steel needle will not touch hard objects such as stones, plan the topsoil according to the required measurement depth, and maintain the original tightness of the soil below. Hold the sensor body and insert it vertically into the soil. When inserting it, do not shake it back and forth, and make sure it is in close contact with the soil. In a small range of a measuring point, it is recommended to measure multiple times to obtain an average.
2、Buried measurement method: vertically dig a pit with a diameter of more than 20 cm, the depth is as required for the measurement, and then insert the sensor steel needle into the pit wall horizontally at a predetermined depth, and bury the pit and compact it to ensure close contact with the soil. After a period of stabilization, measurements and recordings can be made for days, months, or even longer.
This method is used for multi-layer soil moisture detection, and the humidity heads are arranged at a distance of 10cm to prevent mutual interference. Do not shake the sensor when inserting to prevent the sensor probe from being bent and damaging the steel needle.
