Description:

DSM501A PM2.5 Dust Sensor Module can sense tobacco smoke and pollen, house dust, such as a heating automatic suction device, adjustable resistance is set up to detect the size of the dust. Using the same particle counter principle as the foundation, to detect the absolute number of particles per unit volume.

Specifications:

Electrical parameters DSM501 module

High level (clean air) 4.5V (min. 4.0V)
The smallest particle measure capability 1um
Sensitivity 15,000 / 283ml
Operating current (Max) 90mA
Humidity range Storage environment 0-99% RH
Working environment 0-95% RH
Temperature range Storage environment -20 °C to 80 °C
Working environment -10 °C to 60 °C
Settling time Approximately 1 minute after the heater is switched on

Features:

  • PM2.5 Dust Sensor Module can sense tobacco smoke and pollen, house dust and so on
  • PM2.5 Dust Sensor Module can measure 1 micron or more of small particles
  • Small size, lightweight, easy to install
  • 5 V input circuit for signal processing
  • PM2.5 Dust Sensor Module has built-in airflow generator, you can attract the external atmosphere
  • Maintenance is simple and can keep the characteristics of the sensor for a long time

Pin Description:

  • Output Pin Vout2: For the general output pin, the sensitivity has been set, and the smallest particle measure capability is 1um
  • Output Pin Vout1: For the adjustable output pin, the sensitivity can be adjusted by the control pin, the default is 2.5 times Vout2, that is, the smallest particle measure capacity is 2.5um
  • Control Pin: Between this pin and GND a resistor can be adjusted Vout1 minimum particle measure level, adjust the resistance value can be adjusted Vout1 sensitivity.
Resistance Output pin Vout1 sensitivity
NULL Default sensitivity (2.5um or more)
100K Semi-sensitivity (2um or more)
27K The same as Vout1 sensitive (1um or more)

Application Note:

  • Heating capacity: Built-in a heater, heat causes rising airflow so that the outside air enters the module inside.
  • The measure of the particle type: This PM2.5 Dust Sensor Module is set to measure more than 1um particles, such as cigarettes, house dust, mould, pollen, and spores.

Installation:

  • PM2.5 Dust Sensor Module must be mounted vertically
  • Keep away from artificial airflows, such as fans. When used with an air freshener, the front and rear sides of the fan cannot be mounted. Optionally can be mounted on one side, but the vents should be kept in the housing to ensure that external airflow can flow in.
  • Attention to avoid the installation of viscous particles, such as oil into the module, otherwise will cause failure.
  • When the PM2.5 Dust Sensor Module is affected by moisture will affect its normal function, it should avoid dampness.
  • Lenses: Lenses need to be cleaned at intervals of about 6 months depending on environmental conditions. Wipe clean with a cotton swab dipped in water and then wipe dry. Do not use alcohol and other organic solvents to wipe.

Package Included:

1 x PM2.5 Dust Sensor Module DSM501A Dust Sensor for Arduino, Air-Conditioners
