ECA-HJ07automatic weather station
1、 Function
Used for long-term timed collection and recording of environmental temperature, humidity, light, soil temperature, soil moisture, wind speed, wind direction, and rainfall.
2、 Technical features
1. Design of an automatic collector with completely independent intellectual property rights
Technology, its stability and reliability have been fully validated;
2. Easy to operate and maintain;
3. Multiple anti-interference measures such as lightning protection and noise suppression have been adopted, and more than ten reliability design techniques such as derating design, electromagnetic compatibility design, and information discrimination have been adopted in hardware and software design, enabling the automatic station to have a high level of reliability;
4. Low power consumption, with two power supply options of solar energy and AC, improves the environmental adaptability of the instrument;
5. Output data through TF card
3、 Network communication:
ECA-HJ07 has network transmission function, and the main communication modes are: GPRS； Capable of: system user management, device parameter settings, alarm SMS reminder settings, alarm switch settings, remote operation command settings, crop growth monitoring, crop high-yield decision-making, crop growth simulation, climate production potential, real-time record query, historical record query, and alarm message processing; At the same time, when setting up user login, entering the corresponding latitude and longitude can display the location of the instrument installation on the map. When the image on the map is green, it indicates that the instrument remote communication is normal, and when it turns red, it indicates that the instrument remote communication is abnormal; Users have both graphical and visible display modes when querying data; It also has the function of adding sensors, and different types of sensors can be added according to user needs;
