Hand-held weather station sensors introduced
The handheld weather station is a powerful environmental data acquisition and processing system that can contain up to 12 parameters, including temperature, humidity, dew point, light intensity, light quantum, CO2 concentration, wind speed, wind direction, rainfall, soil temperature, soil moisture, Atmospheric pressure, soil pH, EC conductivity and other parameters, covering almost all meteorological parameters, a comprehensive understanding of agricultural meteorological law, providing the most timely and authoritative guidance for agricultural production. Hand-held weather stations have been widely used in agricultural and forestry production and scientific research projects such as farmland, forest farms, and farms.
Hand-held weather stations use sensors to sense changes in environmental factors in the air to obtain corresponding data, and can store up to 500,000 sets of data. In addition, hand-held weather stations manufactured by Top Instruments can also be configured with GPS to provide geographic location. Below we focus on the analysis of various sensor configurations for hand-held meteorological instruments.
The temperature and humidity dew sensor is a composite sensor that contains the three parameters of temperature, humidity and dew point of the calibrated digital signal output. It uses industrial CMOS process micro-processing technology (CMOSens), including a capacitive polymer moisture measuring element and a band gap temperature measuring element, and is implemented on the same chip with a 14-bit A/D converter and a serial interface circuit. seamless connection. The illuminance sensor, which is generally referred to as lux, represents the luminous flux per unit area of ​​the irradiated body surface. The illuminance sensor utilizes the photovoltaic effect of the semiconductor PN junction and a high-precision instrumentation op amp to detect the ambient light intensity. At the same time, the internal temperature compensation circuit enables the probe to obtain the same detection accuracy at different air temperature conditions. The illuminance sensor can also be used to determine the different levels of illumination in the light box as a reference for grading. Carbon dioxide sensor is based on the principle of far infrared absorption developed, suitable for fast, online, sensor selection of carbon dioxide, the strongest absorption band - 4.26um infrared as a light source absorbance, this area can effectively avoid water vapor interference. The direction in which the wind direction sensor swings the leaf tail pointer is the direction of the wind, and the rotation of the leaf is 360 degrees. Therefore, the model with the degree indicates the wind direction (0° to 359°). Light quantum sensors measure the amount of molar photon radiation that is beneficial to photosynthetic (400-700 nm wavelength) plants and are used to measure the average photosynthetically active radiation (PAR) that the sensor can sense. Rain sensor records rainfall per minute, in mm units, the host computer to conduct statistical data in the form of statistics, statistics of the hourly rainfall.
