Below is an all-in-one weather station designed for measuring wind (speed and direction), rain, solar radiation, temperature, and humidity:

The instruments were installed on the rooftop deck of a historical building. A 3-meter-tall pole was used for mounting the anemometer.

The weather station operates independently, powered by a 30 W solar panel. Data is automatically uploaded to a cloud server for remote access.

OTM provides installation and maintenance services for this project.

The following key instruments are used:

Below is a weather station integrated by OTM for outdoor thermal comfort monitoring:

The station measures the following five environmental parameters:

Wind speed and direction
Air temperature and humidity
Globe temperature

These measurements are used for outdoor thermal comfort analysis, such as calculating the Universal Thermal Climate Index (UTCI). The data is automatically logged by the instruments and uploaded to a cloud server.

The following key instruments are used:

We also provided installation and maintenance services for this project.

Shown below is a system integrated by OTM for outdoor micro-environment measurement:

The system consists of the following components:

HD52.3DP17: ultrasonic anemometer for wind speed, wind direction, temperature, humidity, and solar irradiance measurement
TP876.1.I: 50 mm globe thermometer
HD33MT.4: data logger supporting 4G communication

At the customer’s request, we also customized a stand for the system. A similar system was customized by OTM before. The new system has castor wheels and it is easy to move the system around for measurement.

The power consumption of the system is very low. With the internal 3.4 Ah battery, the system can run for around 5 days without charging. The data can be directly downloaded via a USB cable. With a 4G SIM card, it is possible to connect the data logger to the cloud.

Shown below is a Delta OHM HDMCS-100 all-in-one weather station installed at a construction site for weather monitoring.

The instrument measures the following 6 quantities:

Wind speed
Wind direction
Temperature
Humidity
Pressure
Rainfall

The data are automatically uploaded to Delta OHM cloud via 4G. The end users can conveniently view the results with a web browser.

The initial hardware wiring and software configurations were performed by OTM and the end users just needed to do some simple last-step mechanical mounting.
