iot sensors

1.Product introduction of IoT sensors

iot sensors are hardware components that detect changes in the environment and collect data for collecting data from the surrounding environment and transmitting it over the network.Shandong Fengtu Internet of Things Technology Co., Ltd., as an enterprise specializing in the research, development, production and sales of micro meteorological instruments, has been committed to the promotion and application of micro meteorological instruments and meteorological environment solutions.With a complete production chain, a strong technical team and a comprehensive marketing team, the meteorological products we develop and produce such as ultrasonic wind speed and direction meters, five-element micrometeorometers, six-element micrometeorometers and small automatic weather stations have been widely used in In the fields of meteorological monitoring, urban environment monitoring, wind power generation, navigation ships, aviation airports, bridges and tunnels, etc., we have customers all over the country and have achieved good social and economic benefits.

Compared with traditional miniature weather instruments, our products overcome the need for high-precision timers and avoid measurement inaccuracies caused by sensor startup delays, demodulation circuit delays, and temperature changes.

IoT sensors innovatively integrate air temperature, air humidity, atmospheric pressure, wind speed, wind direction, PM2.5, PM10, noise, optical rainfall, and lighting through a highly integrated structure, enabling 24-hour continuous online monitoring of outdoor meteorological parameters., output ten parameters to the user at one time through the digital communication interface.
