RIKA
Ultrasonic Automatic Weather Station /
IoT Sensors Monitor System

(Model No. RK900-12)

Introduction:

RK900-12 mini automatic weather station is a civil integrated weather station independently developed by RIKA that can measure multiple meteorological parameters.  It can simultaneously measure six major meteorological elements such as atomospheric temperature, atomspheric humidity, wind speed, wind direction, air pressure and rainfall.

The rain sensor is inside the top cover, and cannot be seen from outside. It is an advanced small flat radar module, using 24GHz Doppler radar technology to measure the falling speed of rain droplets, and the intensity can be distinguished according to the particle size and falling speed. 

RK900-12 user a low-power chip with a power consumption of only 1.7W, which is especically suitable for solar energy or battery-powered environment with high requirements on power concumption. 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 meteorologicaal system. The outer shell is ASA engineering plastic.
