Related instruments Temperature & humidity, Air speed & wind, Thermal comfort

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.
