+

When the sensor is not exposed to any light at its working frequency, the Vout output has a value equal to VS (power supply). With exposing to a 38 kHz infrared light, this output will be zero. These modules have 3 pins for Vout, VDD, and Ground so it’s very easy to use them in circuits. Find the Code for each Remote Control Button . In this part, we want to set up a connection between the ...

CO2 Monitoring for LEED Credit |

+

In addition, both LEED versions require CO2 sensors to be recalibrated every 5 years, and for the sensors to be accurate to within 75ppm or 5% of the actual CO2 level, whichever is greater. What is different between LEED v3 and v4? The most current LEED certification is v4 and before gaining IEQ points in LEED v4, a “green cleaning” prerequisite has been added for commercial buildings ...
