RK900-12 Ultrasonic Automatic Weather Instrument
RK900-12 mini automatic weather station is a civil integrated weather station independently developed by our company that can measure multiple meteorological parameters. It can simultaneously measure six major meteorological elements such as atmospheric temperature, atmospheric humidity, wind speed, wind direction, air pressure and rainfall.RK900-12 user a low-power chip with a power consumption of only 1.7W, which is especially suitable for solar energy or battery-powered environment with high requirements on power consumption. As a result of the adoption of new technology and new process, the structure is more compact and compact. Solar radiation and solar illuminance detection module can also be selected, which is very suitable for supporting agricultural meteorological system. The outer shell is ASA engineering plastic.
