PMS-A003C High Precision Laser Dust Sensor Module PM1.0 PM2.5 PM10 PMSA003C
NOTICE:
Customized:The version (PMS-A003C) that has the air inlet on the opposite side from the air outlet .
Default:The version(PMS-A003) that has the air inlet near the air outlet .
They have the same technical support.
Main characteristics
* Zero false alarm rate
* Real-time response
* Correct data
* Minimum distinguishable particle diameter :0.3 micrometer
* High anti-interference performance because of the patent structure of six sides shielding
* Optional direction of air inlet and outlet in order to adapt the different design
* Smallest
Overview
PMSA003 is a kind of digital and universal particle concentration sensor, which can be used to obtain the number of suspended particles in the air, i.e. the concentration of particles, and output them in the form of digital interface. This sensor can be inserted into variable instruments related to the concentration of suspended particles in the air or other environmental improvement equipments to provide correct concentration data in time.
Working principle
Laser scattering principle is used for such sensor, i.e. produce scattering by using laser to radiate suspending particles in the air, then collect scattering light in a certain degree, and finally obtain the curve of scattering light change with time. In the end, equivalent particle diameter and the number of particles with different diameter per unit volume can be calculated by microprocessor based on MIE theory. Please find the functional diagram of each part of sensor from Figure 1 as follows.

Output result
Mainly output as the quality and number of each particles with different size per unit volume, the unit volume of particle number is 0.1L and the unit of mass concentration is μg/m³.
There are two options for digital output: passive and active. Default mode is active after power up. In this mode sensor would send serial data to the host automatically .The active mode is divided into two sub-modes: stable mode and fast mode. If the concentration change is small the sensor would run at stable mode with the real interval of 2.3s.And if the change is big the sensor would be changed to fast mode automatically with the interval of 200~800ms, the higher of the concentration, the shorter of the interval.
Typical Circuit
Part
Number Definition
Circuit Attentions
1) DC 5V power supply is needed because the FAN should be driven by 5V. But the high level of data pin is 3.3V. Level conversion unit should be used if the power of host MCU is 5V.
2) The SET and RESET pins are pulled up inside so they should not be connected if without usage.
3) PIN7 and PIN8 should not be connected.
4) Stable data should be got at least 30 seconds after the sensor wakeup from the sleep mode because of the fan’s performance.
Installation Attentions
1) Metal shell is connected to the GND so be careful not to let it shorted with the other parts of circuit except GND.
2) The best way of install is making the plane of in
set
and outset closely to the plane of the host. Or some shield should be placed between inset and outset in order to prevent the air flow from inner loop.
3) The blowhole in the shell of the host should not be smaller than the inset.
4) The sensor should not be installed in the air flow way of the air cleaner or should be shielded by some structure.
5) The sensor should be installed at least 20cm higher than the grand in order to prevent it from blocking by the flock dust.
6) Do not break up the sensor.
Other Attentions
1) Only the consistency of all the PM sensors of PLANTOWER is promised and ensured. And the sensor should not be checked with any third party equipment.
2) The sensor is usually used in the common indoor environment. So some protection must be added if using in the conditions as followed:
a) The time of concentration ≥300μg/m³ is longer than 50% of the whole year or concentration≥500μg/m³ is longer than20% of the whole year.
b) Kitchen
c) Water mist condition such as bathroom or hot spring.
d) outdoor
