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.
