Figure 28 shows the thermocouples attached to the green roof test rig.Figure 28: Green Roof Thermocouple Placement7.14 NI USB-6008The NI USB-6008 Measuring Device provides basic data acquisition for applications such assimple data logging, portable measurements and academic lab experiments.Figure 29: NI USB-6008 Measuring DeviceNiall Carroll Page 50The Thermal and Rainwater Runoff Performance of an Extensive Green Roof System
It was used to acquire the relative humidity (moisture content) of the substrate.For further technical information on the NI USB-6008 see the NI website.7.15 Humidity SensorA Honeywell HIH-4000 series humidity sensor was used to measure the moisture content ofthe substrate on the green roof.Figure 30: HIH-4000 Humidity SensorThe humidity sensor was connected to the NI USB-6008 using a three wire connection via aterminal block.The dimensions and terminals of the humidity sensor are shown in Figure 31.Figure 31: HIH-4000 Dimensions and TerminalsNiall Carroll Page 51The Thermal and Rainwater Runoff Performance of an Extensive Green Roof System
