Speedtech’s air quality sensor monitors indoor air quality, and instantly displays a reading of the value on a scale of 0 (good) to 500 (bad). This value is displayed on the LCD, along with a quick color code, to identify any dangers. The information is also transmitted to the EW-3 weather station, as an additional sensor. Thus, the air quality sensor can be used stand-alone or with the Unlike other “air quality” meters on the market, Speedtech’s sensor is advanced and measures many different air borne particles, including pollen, dust, and other volatile air particles. This is then translated into an easy-to-read number and level.
Operates on AC adapter. Four “AA” batteries can be used for short-term measuring and transmitting, but only last about five hours.
NOTE: The EW-3 will accept five total sensors, any combination of temperature/humidity, UV, and air quality sensors.
