Anemometer is the instrument we use to measure wind speed. Use the hole punch to make one hole in the side of four of the paper cups (all roughly in the same place) and four equally-spaced holes ...

GREENVILLE, N.C. (WITN) - There are numerous weather instruments which are used to measure everything from relative humidity, temperature, dew point, air pressure, wind direction, wind speed, rainfall ...

As HVACR technicians, job number one is ensuring the comfort of the customer. For an HVACR system, it is effective heat transfer and efficient conditioning in all intended zones of the system.

Uncomfortable rooms are among the top comfort problems your customers face. While some rooms are too hot, others are freezing. In some homes, the lack of comfort extends to entire floors. It’s sad ...

All thermal anemometers work by inferring air speed from measurements of thermal impedance (Z) between a heated sensor and the surrounding air: An example of the constant power type can be found in ...

Awhile back I published a simple design idea for a thermal airspeed sensor based on a self-heated Darlington transistor pair. See Figure 1. Figure 1 Older design idea with self-heated Darlington ...
