PMS5003 dust sensor is a particle monitoring device based on the
principle of laser scattering. The main parameters are as follows:
Core parameters
Measurement principle: Laser scattering principle, capable of
accurately measuring suspended particles of different sizes.
Minimum resolution particle size: 0.3 µm.
Particle count efficiency: 50% at 0.3 µm, 98% at ≥ 0.5 µm.
Effective measurement range of particulate matter mass
concentration (PM2.5 standard value): 0 - 500 µg/m³.
Power Supply Parameters: DC supply voltage range 4.5 - 5.5V,
maximum operating current ≤ 100mA, standby current ≤ 10mA.
Performance indicators
Response time: Single response ≤ 1 second, overall response ≤ 10
seconds.
Environmental adaptability: Working temperature -10 to 60℃,
humidity 0 to 95% (no condensation), storage temperature -20 to
80℃.
Data interface: Level output: L < 0.8V (3.3V), H > 2.7V
(3.3V).
Installation and Maintenance
Installation Requirements: The air intake and exhaust ports
should be tightly attached to the air holes of the equipment,
avoiding placement directly in the purification system's duct. The
sensor should be at least 20 centimeters above the ground.
Safety measures: Avoid short-circuiting the metal casing with other
circuits. When used outdoors, additional protection against harsh
weather conditions such as sand, rain, and snow is required.
