Automatic weather station is a kind of equipment widely used in outdoor weather monitoring, forest fire prevention, road traffic, soil moisture and other fields. It has low power consumption, long life and convenient installation.
What are the commonly used sensors in automatic weather stations? Observation parameters need to be customized according to the actual monitoring area. Common ones include wind speed and direction, soil temperature and humidity, air temperature and humidity, ultraviolet rays, solar radiation and so on.
What are the sensors commonly used in automatic weather stations?
Commonly used sensors include soil temperature and humidity, soil nitrogen, phosphorus and potassium, atmospheric pressure, air temperature and humidity, ultraviolet rays, ultrasonic wind speed and direction, etc. Generally speaking, sensors should be customized according to actual needs, because different monitoring environments need to observe different parameters.
1. Ultrasonic wind speed and direction sensor
Wind speed and wind direction are two conventional parameters in meteorological environment monitoring, only need to install ultrasonic wind speed and wind direction sensor. The sensor adopts an integrated structure and has no movable parts as a whole. It measures the wind speed and wind direction data through the time difference of ultrasonic waves propagating in the medium. This type of wind speed and direction sensor has a stable structure and high data accuracy, which can meet the needs of different environmental monitoring.
2. Soil temperature and humidity sensor
For those engaged in agriculture and scientific research, soil temperature and humidity sensors are also very important equipment. The device can monitor the temperature and humidity in the soil in real time, providing scientific data for people to carry out water-saving irrigation and moisture monitoring. The sensor can measure temperature and humidity alone, and can also measure data such as salinity and conductivity at the same time.
3. Soil nitrogen, phosphorus and potassium sensor
Whether the nutrient content in the soil is high or low will have an important impact on the growth of crops, so the moisture station will also monitor the content of nitrogen, phosphorus and potassium through soil nitrogen, phosphorus and potassium sensors. The sensor can quickly measure parameters such as ammonium nitrogen, nitrate nitrogen, available phosphorus, and available potassium in the soil, and can be buried in the soil for a long time to work.
