PPD42NS (Optical Dust sensor Module)
Features:
- Stable and sensitive detection of not only cigarette smoke but also house dust which are indoor asthma triggers.
- Air is self-aspirated with the current of air generation mechanism with a built-in heater.
- Easy maintenance. High sensitivity lasts long term.
- Dual output for the particle size over 1 micron and 2.5 micron (approx).
- More compact and lighter, and easy installation.
Description
This Dust Sensor gives a good indication of the air quality in an environment by measuring the dust concentration. The Particulate Matter level (PM level) in the air is measured by counting the Low Pulse Occupancy time (LPO time) in given time unit. LPO time is proportional to PM concentration. This sensor can provide reliable data for air purifier systems; it is responsive to PM of diameter 1μm.
Note:
This sensor uses counting method to measure dust concentration, not weighing method, and the unit is pcs/L or pcs/0.01cf.
Features:
- Grove compatible interface(extra wire with connecter)
- Supply voltage range: 5V
- Minimum detect particle: 1um
- PWM output
- Dimensions: 59(W)x45(H)x22(D) [mm]
Application Ideas:
- Air Purifier
- Air Quality Monitor
- Air Conditioner
- Ventilator

MQ-8 (Hydrogen Gas Sensor Module)
MQ-8 Sensor Information: sensitive material MQ- 8 gas sensors used in clean air, low conductivity tin oxide (SnO2). When there is an environment in which the combustible gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases. Use simple circuit can convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-8 hydrogen gas sensor of high sensitivity monitoring of other hydrogen-containing gas is also very good. The sensor can detect a variety of hydrogen-containing gas, in particular, city gas, is a low-cost sensor suitable for a variety of applications.
