Knowing the exact content of PM is of the utmost importance to follow the WHO air quality guidelines recommending exposure limits to key air pollutants and reduce their adverse health effect on human being.

Cost effective and reliable, PMsense is the perfect solution in smart city applications and environmental monitoring especially close to sources of PM such as construction sites, industrial activities, smokestacks, power plants, combustion engines, road traffic

Based on laser scattering measuring principle, PMsense ensures a very accurate reading of PM1.0, PM2.5 and PM10 particle counts.

The configuration of the instrument and the reading of the measurements can be done via the RS485 serial output, both with the proprietary protocol and with the MODBUS-RTU protocol and the results are reported in μg/m³. In combination with one of our loggers, collected data are then sent via HTTP to the Senseca Cloud and therefore available on any device.

As a producer of Automatic Weather Stations, we also recognize the demand from the market in having PM measurement in combination with an AWS. The PMsense is ready to be fully integrated: simple and fast, plug and play without any further start up. By incorporating this measurement in AWS we can provide early warnings when air pollution is getting close to the danger zone.

If you are looking for a version for inside measurement and detection, go here to see full details of our HD50PM data logger for indoor.

Particulate Matter (PM) also called Particle Pollution.
An explanation of the term PM, as found on the site of the EPA (United States Environmental Protection Agency): the term for a mixture of solid particles and liquid droplets found in the air. Some particles, such as dust, dirt, soot, or smoke, are large or dark enough to be seen with the naked eye. Others are so small they can only be detected using an electron microscope.

What does the number behind PM stand for:
The number stands for the size of the particle, expressed in micro-meters.
So: PM1.0 means the collection of measured particles that have a diameter of 1µm or less. Talking about PM10 means that we take in consideration all particles with a size of 10µm or smaller.

Why is it interesting to know the PM:
The particles that we talk about are that small that we (can) inhale them without noticing. But the effect of inhaling them can have dramatic consequences. Especially particles smaller than PM2.5 are considered to be dangerous for human health; they can get deep into your lungs or may even get into your bloodstream.

Where does this Pollution comes from:
Some of the particles are being formed by human interaction, some are the result of reactions of spontaneous reactions of chemicals that are in the atmosphere. The ones that are being emitted as result of human interaction can be found in areas with high industrial activity, fires, smoke, construction sites or in areas with high activity of cars and transport.

Particulate Matter Pollution:
The datalogger that Senseca has introduced measures the Air quality inside buildings. Senseca will also introduce an outdoor version that will be combined with our AWS (Automatic Weather Station). Buildings where it is likely to face problems with air quality are e.g. the ones near heavy traffic situation in cities or highway areas. Or as another example, offices connected to industrial workplaces in steel mills, cement factories or other production areas.

Let it be clear:
Measuring the Air Quality is highly important when we care about health. Based on the measurement we can take temporarily measures (ventilation or even working on other spots) or we can use it to improve air conditioning and filtering of the air.

Interested? Have a look at the specifications of the HD50PM – very simple to install (power and a WiFi or cables network will do). Can be used with cloud storage, in a network of loggers or as stand-alone unit. Or just ask us for more information.

Senseca will also introduce a version for outside measurement and detection.
