Pdsm010 particle sensor module product summary Pdsm010 detects approx. 1m particle such as house dust, pollen, germs, dust mites and cigarette smoke and measures the concentration of floating particles in a room space up to maximum 30m3. This sensor is an ideal product for automatic room air monitoring system such as an air purifier. Pdsm010's signal is converted to pwm output by internal circuit and mcu program. Also, the sensor's filter circuit and mcu program can remove a noise in order to operate more stably when a noise is in-flowed in the signal. Pdsm010 has advantages of both stable detecting ability and high manufacturing efficiency. The sensor does not have an additional control point (vr trimmer) on the device unlike its previous model (dsm). It prevents potential malfunction often occurred by user's arbitrary modification. Pdsm010 particle sensor module features * customized sensitivity for efficient control in application * detects approx. 1m particle * mcu control (factory calibration) * easy maintenance * pwm output (low logic pulse active) * noise protection Pdsm010 particle sensor module applications * air cleaners, air conditioners * ventilation system, fan control * iaq monitoring & control * iot device Pdsm010 particle sensor module product specification * supply voltage: 5v 10% v * supply current (@ 5v): < 85ma * storage temperature range: -20 ~ 80'c * operating temperature range: -10 ~ 65'c * operating humidity range: < 95%rh
