HONEYWELL IH-PMC-001

IH-PMC-001 is an IPM series intelligent particulate matter sensor. It is a laser-based sensor that detects and measures particle concentration using light scattering for monitoring air quality. The detection concentration range is 0µg/m3 to 1,000µg/m3. A laser light source illuminates a particle as it is pulled through the detection chamber. As particles pass through the laser beam, the light reflects off the particles and is recorded on the photo or light detector. The light is then analysed and converted to an electrical signal to calculate particle concentration. During the production calibration process, the sensor records the original laser light intensity parameters and fan speed. The calibration algorithm is applied to the sensor output to minimize sensor drift and improve accuracy over the sensor's lifetime. Applications include air quality monitors (indoors, outdoors), air purifiers (commercial, residential), automotive cabin air purifiers and HVAC (commercial, residential).
