The LEED standard recognizes the usefulness of CO2 to monitor Indoor Air Quality. But did you know that the LEED standard for new construction includes provisions for measuring CO2 levels outdoors? – Outdoor Air Delivery Monitoring, a possible credit in the United States Green Building Council’s LEED Certification for New Construction, calls for either carbon dioxide monitors or ...
Multi-function. Simultaneous measurement of up to eight (8) key IAQ indicators with one probe; VOCs, CO 2 (dilution ventilation), CO, O3, NO2, %RH, °C/°F plus an additional toxic gas sensor (from a broad choice of specific gases) Optional particle concentration (PM , PM , PM 10, TSP plus 2 other size ranges) With an added probe, concurrently measure up to six additional gases
· In this tutorial, we will learn a little bit about Sensors and Transducers, how to choose a Sensor, requirements of Sensors and Transducers, what are the classification of sensors, few examples of both Analog and digital sensors. We live in an Analog World with Digital means of communication and control Mechanical objects with Electrical signals. This is possible because of …
· LEED Building Information. As a result of a 2006 evaluation by GSA of sustainable building rating systems, the Administrator concluded that Leadership in Energy and Environmental Design (LEED®) remains the most credible rating system available to meet GSA’s needs. The Energy Independence and Security Act of 2007 (EISA) requires GSA to re-evaluate the rating systems every …

· Infrared touch sensor measures touch through whether the emitting LED beam is broken or changed when an object makes contact with it. Commonly used in kiosks or gaming applications, infrared touch sensors are long-lasting and insensitive to pressure (similar to capacitive touch sensor) Surface acoustic wave (SAW) touch sensor. As its name suggests, the SAW touch sensor measures the …

S4000CH/S4100C Intelligent Sensors •Microprocessor-based transmitter designed for use with our reliable catalytic-bead sensors. •Remote mounting of sensor increases installation flexibility. •3 digit LED display shows gas concentrations in % LEL, fault codes for troubleshooting and calibration prompts.
· Simply power the module with 5V and you should notice the power LED on the module to glow and when no gas it detected the output LED will remain turned off meaning the digital output pin will be 0V. Remember that these sensors have to be kept on for pre-heating time (mentioned in features above) before you can actually work with it. Now, introduce the sensor to the gas you want to detect …

LEED projects are responsible for diverting over 80 million tons of waste from landfills. Compared to the average commercial building, LEED Gold buildings in the General Services Administration’s portfolio consume a quarter less energy and generate 34% lower greenhouse gas emissions.
· Sensor design Although the application of IR LEDs leads to poorer optical properties in comparison to diode lasers, LEDs enable CO2 measurements in the μm region almost without cross sensitivities while they can greatly reduce the overall costs. The spectral bandwidth of the LEDs covers the CO2 absorption line but is still narrow enough to avoid noticeable interactions with other gas ...
· MQ5 Gas Sensor. by shedboy71 26th March 2016. The MQ5 Gas Sensor module is useful for gas leakage detection. It is suitable for detecting H2, LPG, CH4, CO, Alcohol. Due to its high sensitivity and response time, measurements can be taken as soon as possible. The sensitivity of the sensor can be adjusted by using the potentiometer.
· Each control device shall control no more than 2,500 sq ft for a space of 10,000 sq ft or less and a maximum of 10,000 sq ft for a space greater than 10,000 sq ft. Controlled lighting shall have at least one control step between 30% and 70% in addition to all-off.
Green Building Programmes – BREEAM, LEED, Energy Technology List (UK). Better Performance Murco Gas Detectors offer reliable, real-time and continuous monitoring.

Check local regulations on calibration or testing requirements. After exposure to a substantial gas leak, the sensor should be checked by bump test or calibration and replaced if necessary. Location: For all gas’ heavier than air, Danfoss recommends locating the sensor head app. 30cm (12") above the floor and if possible in the air flow. All gas’ measured with these DGS-sensors are heavier ...
· This is first hand knowledge that LEED does not appear to waive any restrictions for # or people or room size, all that matters is the the occupancy density requirement is met. Any space with less that people/sqft does not need a CO2 sensor and any space greater than than density needs the sensor if applying for this credit with the CO2 sensor option selected.
