the sensor. When a warm object like a person passes by, the sensor detects the heat, which causes a positive diferential change between the two halves of the sensor. When the warm body leaves the sensing area, the sensor generates a negative diferential change. These change pulses are what is detected. The assembly is contained in a housing with
Indoor Air Quality in Classrooms and COVID19. April 12, 2021. The effect of poor indoor air quality in classrooms has been known for years.
