Connecting PMS7003 sensor
The sensor has ten pins, their description is shown in the table.
| Pin | Description |
|---|---|
| Pin 1 | VCC - 5V power supply. |
| Pin 2 | VCC - 5V power supply. |
| Pin 3 | GND - Ground. |
| Pin 4 | GND - Ground. |
| Pin 5 | Reset of the chip after low state is given - operates with 3.3 V. |
| Pin 6 | NC. |
| Pin 7 | RX - UART receiver - operates with 3.3 V. |
| Pin 8 | NC. |
| Pin 9 | TX - UART transmitter - operates with 3.3 V. |
| Pin 10 | SET - sleep after high state is given, works with 3.3 V. |
The device works with 3.3 V, to connect with a device working with higher voltage we recommend using voltage converter. Module has 1,27 mm pinout, we offer dedicated adapter for 2,54 mm pinout and adapter for JST 1,25 mm pinout. |

PM1.0 / PM2.5 / PM10 particulate matter sensor - PMS7003 - 3.3 V UART
The dust sensor module allows you to track parameters determining the degree of cleanliness of the air in terms of PM1.0, PM2.5 and PM10 particles. The built-in measurement sensor enables the detection of particles with a diameter of 0.3 μm and above, such as components of tobacco smoke or exhaust fumes emitted by motor vehicle engines. The PMS7003 sensor requires a stabilized voltage supply of 5 V. Communication between the sensor and the microcontroller is via the UART interface, which operates at voltages with a logic level of 3.3 V.
Application of air quality sensor
The PMS7003 is a digital measurement sensor that measures the concentration of particulate matter in the air and converts this information into a digital form that is readable by the microcontroller receiving data from the sensor. The PM7003 sensor can be used in environmental applications such as airborne particulate measurement systems, as well as in advanced real-time air quality monitoring systems.
PMS7003 sensor principle of operation
The PMS7003 sensor operates on the principle of laser light emission and scattering. The laser beam produced by the sensor is used to illuminate the air to capture the particles in it. Based on the number of particles captured by the laser light, a processor embedded in the sensor approximates a curve representing changes in light scattering in the time domain. In the next step, the algorithm calculates the number of particles and their diameter per unit volume in the air, according to the Mie solution theory.
Sensor connection
The offered measurement module, based on the PMS7003 sensor, has a 10-pin IDC male connector. In order for the module to work with host devices (e.g. Arduino or Raspberry Pi based controllers), it is necessary to connect a special adapter, which has pins compliant with UART interface specification.
Such converters are also available in Botland shop, in 1.25mm and 1.27mm pinout versions.
Sensor communication with external devices
PMS7003 sensor measurement module uses UART interface for communication. This is one of the most commonly used communication standards in embedded systems.
UART uses four pins, i.e. power supply (VCC - supply voltage, in this case 3.3V and GND - supply ground) and communication lines for data exchange (RX - UART receiver and TX - UART transmitter). Thanks to this, the module can work with Arduino and Raspberry Pi.

Question: Does the sensor come with a cable? (I mean the specific cable that connects to the adapter.)
Question: Good day is it possible to connect this sensor under raspberry pi zero 2? Because technically it is powered on 3.3V but I dont know if it is possible and how to adapt UART input under GPIO to work with raspberry pi.
