Multiparameter Weather Sensor

1.Multiparameter Weather Sensor Product Introduction

Multiparameter Weather Sensor is a robust, all-in-one weather sensor that measures wind speed, wind direction, atmospheric pressure, temperature and relative humidity.

Compared with traditional micro-meteorological instruments, our products overcome the need for high-precision timers and avoid inaccurate measurements caused by sensor startup delays, demodulation circuit delays, and temperature changes.

HM-WQX8 eight-element micro-meteorological instrument innovatively realizes the standard meteorological parameters (wind speed, wind direction, temperature, humidity, air pressure, PM2.5, PM10, noise) through a highly integrated structure, which can realize 24-hour continuous online monitoring of outdoor meteorological parameters and output the eight parameters to the user at one time through the digital communication interface. The product has a compact structure, beautiful and elegant appearance, and is highly integrated.

2. Multiparameter Weather Sensor Product Features

1. The top cover hides the ultrasonic probe to avoid interference from rain and snow accumulation and avoid being blocked by natural wind (utility model patent, patent number ZL 2020 2 3215713.X)☆

2. The principle is to emit a continuous frequency-variable ultrasonic signal and detect wind speed and direction by measuring the relative phase (invention patent, patent number ZL 2021 1 0237536.5)☆

3. Wind speed, wind direction, temperature, humidity, air pressure, PM2.5, PM10, noise eight elements integrated (utility model patent, patent number ZL 2020 2 3215649.5)☆

4. Using advanced sensing technology, real-time measurement, no start-up wind speed☆

5. Strong anti-interference ability, with watchdog circuit and automatic reset function to ensure stable operation of the system

6. High integration, no moving parts, zero wear

7. Maintenance-free, no need for on-site calibration

8. ASA engineering plastics are used for outdoor applications without discoloration all year round.

9. The product design output signal is standardly equipped with RS485 communication interface (MODBUS protocol); 232, USB, Ethernet interface are optional, supporting real-time data reading☆

10. Optional wireless transmission module, minimum transmission interval 1 minute

11. The probe adopts a snap-on design, which solves the problem of looseness during transportation and installation.
