Honeywell HPM Series Particulate Matter Sensors

HPM series particulate matter sensor: high-precision laser scattering technology empowers air quality monitoring

With the increasing attention to air quality, real-time monitoring of particulate matter concentration has become an important functional requirement in the fields of environmental monitoring, HVAC systems, air purification equipment, and smart homes. The Honeywell HPM series particulate matter sensors are an ideal choice for various air quality monitoring applications due to their laser scattering detection principle, high-precision output, long-life design, and industrial grade electromagnetic compatibility performance.

Product Overview and Technical Principles

The HPM series particle sensor is a particle detection device based on the principle of laser scattering. Its working method is as follows: the air sample is sucked into the detection chamber through an internal fan, and the laser light source irradiates the particles in the airflow. The light reflected by the particles is received by the photodetector, and the system analyzes and converts the light signal into an electrical signal, finally calculating the concentration of particles per unit volume.

The detection concentration range of this sensor is from 0 μ g/m ³ to 1000 μ g/m ³, covering a wide range of application needs from clean environments to high pollution scenarios.

Product model and output configuration

The HPM series offers two external dimensions, standard and compact, to meet different installation space and system integration requirements:

Model Description

HPMA115SO-XXX standard size, UART output, PM2.5 and PM10 output

HPMA115CO-003 compact size, UART output, inlet and outlet on the same side

HPMA115CO-004 compact size, UART output, inlet and outlet on opposite sides

The standard version provides PM2.5 and PM10 concentration outputs, while the compact version adds PM1.0 and PM4.0 outputs to provide users with richer particulate matter classification data.

Core technical specifications

1. Detection accuracy

The HPM series has high-precision measurement capabilities in different concentration ranges:

Range of 0-100 μ g/m ³: PM2.5 accuracy is ± 15 μ g/m ³

Range of 100-1000 μ g/m ³: PM2.5 accuracy of ± 15%

Compact versions PM1.0, PM4.0, PM10: accuracy within the range of 0-100 μ g/m ³ is ± 25 μ g/m ³, and accuracy within the range of 100-1000 μ g/m ³ is ± 25%

2. Response time

The sensor response time is less than 6 seconds and can reflect real-time changes in environmental particulate matter concentration, making it suitable for dynamically adjusted air purification and ventilation systems.

3. Electrical characteristics

Supply voltage: 5 V ± 0.2 V

Maximum operating current: 80 mA

Standby current:<20 mA (at 25 ° C)

Maximum surge current: 600 mA

Output protocol: UART, baud rate 9600, 8 data bits, 1 stop bit, no checksum

To ensure power stability, it is recommended to configure 22 μ F electrolytic capacitors and 100 nF and 10 nF ceramic capacitors at the power output end to reduce ripple and noise effects.

4. Environmental adaptability

Storage temperature: Standard version -30 ° C to 65 ° C, Compact version -40 ° C to 85 ° C

Working and storage humidity: 0% RH to 95% RH, non condensing

Laser safety level: Class 1, compliant with IEC/EN 60825-1 standard, wavelength 650 nm

5. Electromagnetic compatibility performance

The HPM series has undergone rigorous electromagnetic compatibility testing and meets the requirements of the industrial standard IEC61000 series

ESD: ± 4 kV contact discharge, ± 8 kV air discharge

Radiation immunity: 1 V/m (80 MHz to 1000 MHz)

Fast transient pulse: ± 0.5 kV

Conducted immunity: 3 V

Radiation emission: Complies with CISPR 14 standard

This performance enables it to operate stably in industrial environments, avoiding measurement errors caused by electromagnetic interference.

Key differentiation advantages

1. 10-year continuous service life

The HPM series sensors use high-quality optical components and optimized circuit design, which can achieve a service life of up to 10 years in continuous operation mode. This feature significantly reduces the frequency of equipment maintenance and replacement costs, especially suitable for application scenarios that require long-term online monitoring.

2. Industrial grade EMC performance

Based on the IEC61000 standard, the electromagnetic compatibility design ensures that the sensor can maintain a PM2.5 measurement accuracy of ± 15% even in strong electromagnetic interference environments such as motors, frequency converters, and wireless communication devices, providing reliable guarantees for industrial and commercial applications.

3. Quick response

A response time of less than 6 seconds enables the sensor to track changes in air quality in real time, providing real-time feedback for air purification equipment and improving system control efficiency.

4. Flexible installation methods

The HPM series offers two sizes: standard and compact. The compact version also provides two configurations for inlet and outlet on the same side and opposite side, adapting to different equipment structures. The installation direction has been optimized to effectively prevent the accumulation of particulate matter at the inlet and outlet, ensuring long-term measurement accuracy.
