An array of temperature probes will be used to monitor the ISU clean room's temperature and humidity, with one probe being a temperature and humidity probe.
Five probes will be used for basic temperature monitoring. These probes are the Sensatronics's Standard Temperature Probe and will cost $60.50 each.
ISU already possesses the Sensatronics's Temperature-Humidity Combo Probe which will be used to monitor the temperature and humidity in the center of the room.
The thermometer's analog output is converted to a digital signal using the Sensatronics Model EM1 Environmental Monitor. This device supports up to 12 monitoring probes and has a built-in web server to transmit its data over the network upon request. This device will cost $438.90.
The total cost will be approximately $760.00 for temperature monitoring in the ISU clean room. The temperature probes will allow for real time temperature monitoring with web access to the data. This data will be plotted using the same system as the BREMS cluster located at ISU.

Clean Room entry doors
These are the entryway doors donated by ON semiconductor for the ISU clean room. They will be fitted together to form an air shower device for entering the clean room.
Temperature Monitoring
Continuous temperature and humidity monitoring has been performed in the ISU clean room for the past month.
The data so far show a 2 degree Fahrenheit temperature deviation in the clean room. These fluctuations are within the accepted fluctuation deviation required for the construction of the R1 drift chambers.
The humidity has been fluctuated more than the temperature, but has remained consistently well below the 55% requirement.
R2 Stringing Platform

Here is the design sent to ISU of the R2 stringing platform. It is currently believed that it should fit in the ISU clean room for the purpose of stringing the R1 wire chambers.

Received pdf schematics of the R2 Stringing platform. It appears that it will be able to fit in the ISU clean room without a problem. If the size could be reduced without sacrificing functionality, that would still be beneficial.
