gas-detection - PyPI

· The MQ-2 sensor can detect multiple gases (CO, H2, CH4, LPG, propane, alcohol, smoke) and outputs analog voltage. This project can convert it to digital using ADS1015 or ADS1115 and filter out the target gases. The sensor can be inaccurate so don't use those measurements if you need them for security purposes.

LED als Lichtsensor

Eine LED als Lichtsensor. Eine LED kann nicht nur Licht erzeugen, sondern auch Licht erkennen! Die arbeitet dabei ähnlich wie eine Fotodiode. Photonen befreien Elektronen in der Sperrschicht der Diode. Dabei fließt ein größerer Sperrstrom , wenn die LED beleuchtet wird. Weil der Sperrstrom einer LED sehr klein ist, wird ein zusätzlicher Transistor zur Verstärkung eingesetzt. Der Aufbau ...

LEED NC (BD+C) - High Rise Residential Building - CO ...

· My understanding is that for LEED compliance you should pursue ASHRAE , so an exhaust ventilation scheme with dedicated kitchen exhaust. That's the feedback I've gotten from USGBC, but they haven't yet issued any formal statement about meeting ventilation requirements in MF that I know of. I would encourage you to follow-up with them directly via the LEED Coach and LEED info …
