Soil temperature and moisture sensor introduction:
Soil temperature and moisture sensors, also known as ground temperature sensors, are devices used to measure soil temperature and moisture, mainly supporting automatic weather stations, soil moisture detection and other fields. Soil temperature and moisture measurements are important for fields such as agriculture, ecology and environmental monitoring to help people understand the health of the soil and moisture utilization so that they can make decisions accordingly.
Classification of soil temperature and moisture sensors:
The working principle of soil temperature and moisture sensors can be divided into several types, including resistive, capacitive, oscillatory and microwave type. Resistive sensors are the most common type and are relatively inexpensive, typically ranging from a few tens to hundreds of dollars. Capacitive and oscillatory sensors are slightly more expensive, but more accurate. Microwave sensors are typically used for long-range measurement and monitoring of soil moisture and are more expensive, typically in the thousands of dollars or more.
Soil temperature sensors work on the following principles:
Soil temperature sensors: use the thermistor or thermocouple principle to determine the soil temperature by measuring the resistance value or potential difference.
Soil moisture sensor: Using the principles of capacitance, resistance and echo, soil moisture is determined by measuring the capacitance value, resistance value or acoustic echo time.
the soil temperature and moisture sensor application scenarios
Soil temperature and moisture sensors are widely used in agriculture, ecology, environmental monitoring and water management. By measuring soil temperature and moisture, they can help farmers to manage their farmland and irrigation wisely, improve soil quality and increase crop yield. In ecology and environmental monitoring, soil temperature and moisture sensors can help us understand the health of land and vegetation and provide data to support environmental protection and ecological restoration efforts.
Soil temperature and moisture sensors are widely used in scientific research, environment, agriculture, forestry, water-saving irrigation, greenhouse greenhouses, flowers and vegetables, grassland pastures, soil quick measurement, plant culture and various fields of particulate matter water content and temperature.
1. Agricultural production: It can be used for soil temperature and humidity monitoring during the growing period of crops to provide scientific data support for agricultural production.
2. Forest fire prevention: It can be used in forest fire prevention early warning system to monitor the temperature and humidity condition of forest area in real time.
3. Environmental monitoring: It can be used for soil temperature and humidity monitoring in urban parks, green belts and other environments to provide data support for environmental protection.
4. Hydrological monitoring: It can be used for monitoring soil temperature and humidity around rivers, lakes and other waters, providing data support for hydrological monitoring.
Soil temperature and moisture sensor use method:
Usually buried in the soil surface layer, but also can be measured in layers. A hole of ideal depth can be excavated using an earth auger at the selected test point on the ground and the sensor can be buried in it. Long-term field observation is possible.
