In this project, the following instruments were integrated to monitor solar radiation, daylight, thermal comfort and weather:

• LPPYRA03 spectrally flat class C pyranometer
• LPPHOT01 indoor lux sensor
• LPPHOT03 outdoor lux sensor
• HD9008TRR temperature & humidity transmitter
• TP875.I globe thermometer
• HD403TS2 omni-directional hot wire airspeed transmitter
• HD52.3D ultrasonic anemometer

All instruments were mounted on tripod. Delta Ohm HD35 wireless data loggers were used to record the readings.

For this project, OTM provided full installation and data reporting service.

In this project, the following instruments were integrated for thermal comfort monitoring:

• HD9008TRR temperature & humidity transmitter
• TP875.I globe thermometer
• HD403TS2 omni-directional hot wire airspeed transmitter

All instruments were mounted on a base. Delta Ohm HD35 wireless data loggers were used to record the readings.

The system was designed and integrated by OTM.

Shown below are two sets of Delta Ohm HD32.3TC thermal comfort data loggers. They measure air temperature, humidity, speed, and globe temperature and calculate PMV/PPD/WGBT/turbulence according to ISO standards.

The instruments are with large touch screen and built-in Li-ion battery.
