Reference applications

Expand one of the blocks below for some reference applications.

Application 1: monitoring of solar radiation, daylight, thermal comfort and weather

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

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.

Application 2: solar radiation monitoring on rooftop

In this project, Delta Ohm LPPYRA03 spectrally flat class C pyranometer was installed on a rooftop for solar irradiance monitoring.

The pyranometer outputs mV signal and a Delta Ohm HD35 wireless data logger was used to record the readings.

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

Application 3: monitoring of solar radiation and daylight transmission through glass

In this project, Delta Ohm LPSILICON-PYRA04 silicon pyranometer, LPPHOT01 indoor lux sensor and LPPHOT03 outdoor lux sensor were used to monitor the solar radiation and daylight transmission through a thermochromic glass.

Custom mounting accessories were used to temporarily install the sensors on both the front and back sides of the glass.

The sensors output mV signal and a few Delta Ohm HD35 wireless data loggers were used to record the readings.

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

Application 4: wind monitoring on rooftop

In this project, Delta Ohm HD52.3D ultrasonic anemometer was installed on a rooftop for wind speed and wind direction monitoring.

The instrument outputs 4 – 20 mA signals and a Delta Ohm HD35 wireless data logger was used to record the readings.

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

Application 5: integrated thermal comfort monitoring station

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

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.

Application 6: pyrgeometer with wireless data logger for far infra-red radiation measurement

In this project, the following instruments were integrated for far infra-red radiation monitoring:

The system was wired and configured by OTM. Refer to this blog post for more details.

Application 7: on-site glass optical & thermal property monitoring system

A system was integrated by OTM for on-site glass optical & thermal property monitoring, with the following instruments:

In additional to system integration, OTM also provided monitoring service with detailed report on project completion.

Refer to this blog post for more details: On-site glass optical & thermal property monitoring system.

Application 8: PM1.0, PM2.5 & PM10 measurement with wireless data logger

In this application, the following instruments were integrated for far infra-red radiation monitoring:

The system was wired and configured by OTM. Refer to this blog post for more details.

Application 9: on-site solar irradiance & daylight illuminance monitoring system

A monitoring system was integrated and configured by OTM for on-site solar irradiance and daylight illuminance monitoring. The following Delta Ohm products were used:

Application 10: All-in-one weather station for weather and air quality monitoring

In this application, the following instruments were integrated for weather and air quality monitoring:

More than 10 such stations were installed in different locations in Singapore. OTM provides integration, installation, and maintenance services. Shown below is an example of the installations.

Application 11: LoRaWan data logging system for long distance transmission

In this application, a LoRaWan based wireless data logging system was deployed by OTM. The system consists of:

The system was fully integrated and configured by OTM. OTM also provides 1.5 years of maintenance and data collection services.

The instruments are distributed in various locations of two buildings. Shown below are two important instruments of the system (left: a LoRaWan data logger; right: the LoRaWan gateway).
