Product Description: Sensor for dust / air pollution, formaldehyde, temperature, humidity PM2.5 - PMS5003

Multifunctional sensor that not only checks air quality but also measures temperature and humidity. Combines electrochemical probe for formaldehyde and sensor for temperature and humidity.

Working principle

Such a sensor uses the principle of laser scattering of airborne particles, then collecting the scattered light to a large extent and finally obtaining the scattered light curve. Uniform particle diameter and number of particles with different volume diameter are calculated by microprocessor based on MIE theory. Below is a schematic of the sensor operation.

Sensor terminals

Sensor is compatible with Arduino module, it has UART serial communication pins

PMS5003ST - Multifunction sensor

PMS5003ST is a multifunction sensor that is designed to detect not only particle and formaldehyde concentration, but also to measure temperature and humidity values. As a particulate concentration sensor, it can be used to measure the number of airborne particles using a laser. What distinguishes the PMS5003ST sensor from other popular designs is also an electrochemical probe for measuring formaldehyde concentration and a single chip temperature and humidity sensor.

Applications of PMS5003ST sensor

The sensor can be placed in a variety of measurement instruments designed to study environmental parameters in the air, as well as other instruments to evaluate environmental pollution parameters, to provide the necessary measurement data in real time. The advantage of the PMS5003ST multifunction sensor is its ability to detect particulate matter from 0.3µm in diameter upwards. The offered PMS5003 sensor is ideal for measuring dust/air pollution, formaldehyde, temperature, humidity PM2.5.
