Reference applications
Expand one of the blocks below for some reference applications.
In this application, the following instruments were integrated for far infra-red radiation monitoring:
- Delta Ohm PMsense particulate matter transmitter with MODBUS-RTU output
- Delta Ohm HD35EDW-MB wireless data logger supporting MODBUS-RTU output
The system was wired and configured by OTM. Refer to this blog post for more details.
In this application, the following instruments were integrated for weather and air quality monitoring:
- HD52.3DP17 ultrasonic anemeter: for wind speed, wind direction, temperature, humidity and solar irradiance measurement.
- PMsense particulate matter transmitter: for PM1.0, PM2.5 and PM10 measurement
- HD33MT.4 data logger: with 4G connectivity
- Solar panel and tripod
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.
In this application, an HD50 web data logger with an integrated CO2 probe was configured by OTM for CO2 level monitoring in an indoor space. The objective is to follow the advisory by NEA and BCA (document 1, document 2) to use CO2 level as a proxy to check the ventilation adequacy in an indoor space.
The end user just needed to do some simple last-step mechanical mounting. OTM performed all configurations before delivery. The end users need not to install and learn any software, as they can conveniently access the monitoring results from a cloud portal with a browser. Shown below are some results plotted in the cloud portal:
Shown below are two wireless data loggers for PM1.0, PM2.5, and PM10 measurements. The instruments will be deployed by a construction company for construction site dust level monitoring.
The sensing part and data logging part are integrated into a single instrument. The instrument is rain-resistant and can be deployed outdoors. For mechanical mounting, the instrument can be clamped onto existing structures with 40 mm diameter. The instruments will be pre-configured before delivery and briefing on the basic operations will be provided.
