Types of sensors used in modern agriculture: temperature sensor/humidity sensor/gas sensor/pH sensor

Sensors play a vital role in the development of smart agriculture. So, what are the common agricultural sensors? Soil temperature and humidity sensor, carbon dioxide sensor, soil pH sensor

LoRa environmental sensors refer to LoRa nodes equipped with environmental sensors, such as temperature sensors, humidity sensors, air pressure, indoor air quality sensors, etc. However, unlike traditional environmental sensors, LoRa environmental sensors will collect data It is sent to the LoRa gateway through the LoraWan/LinkWan protocol, and finally sent to the server.

The application of soil moisture monitoring system can measure soil water content and soil temperature at regular and fixed points, and provide data support for the monitoring of seedling, insect and water conditions of crops.

Soil moisture sensor, also known as soil moisture sensor, soil moisture sensor. The soil moisture sensor is composed of stainless steel probes and waterproof probes, which can be buried in soil and dams for a long time to perform fixed-point monitoring and online measurement of soil moisture in surface and deep layers.

The monitoring and forecasting of farmland soil moisture by soil moisture monitoring stations has become an important part of farmland water-saving technology promotion and information services, and plays an important role in comprehensively promoting the application of refined agricultural technology and production management.

NiuBoL soil moisture monitoring system can realize long-term continuous monitoring of soil moisture. Users can flexibly arrange soil moisture sensors according to monitoring needs; they can also arrange sensors at different depths to measure soil moisture in profiles.

The role of small meteorological observatories in agriculture, industry and forestry? In different fields, instruments play different roles. The agricultural field is mainly used to understand the weather and soil moisture, while the forest field is mainly used for fire prevention and disaster prevention.

What is the role of the farmland microclimate observation station? This instrument can usually help people understand the changing trends of moisture content, seedling situation and disaster situation in the farmland, and facilitate people to formulate various countermeasures.

working principle of the ultrasonic wind speed sensor is to use the ultrasonic time difference method to measure the wind speed. Because of the speed of sound in the air, it will be superimposed with the speed of the airflow in the wind direction. If the ultrasonic wave travels in the same direction as the wind, its speed will increase;
