Plantower is a manufacturer of laser particulate matter sensors. At Botland you will find the PMS1003, PMS3003, PMS5003, PMS7003 and PMS9103 models, as well as other sensors that measure PM1.0, PM2.5 and PM10. You can power them with 5 V and connect them via UART. They work well in air quality stations, air purifiers and DIY projects with Arduino, ESP32 or Raspberry Pi.

Plantower: laser particulate matter sensors

Plantower is a manufacturer of laser particulate matter sensors. Sensors from this brand measure the concentration of PM1.0, PM2.5 and PM10 particles, the dust fractions that most often describe air quality. At Botland you will find the PMS1003, PMS3003, PMS5003, PMS7003 and PMS9103 models, as well as other sensors from this series. You can browse the full range in the air quality sensors category.

Plantower air quality sensor: how to choose a model

Model names start with PMS, and the following digits distinguish the sensor versions. Examples are the Plantower PMS5003 and Plantower PMS7003, along with the PMS1003, PMS3003 and PMS9103.

Before you choose an air quality sensor for your project, compare the product pages:

• dimensions and the way of mounting in an enclosure
• connector type and the set supplied with the sensor
• technical documentation (datasheet) describing the data sent by the sensor

Plantower sensors from the Botland range measure PM1.0, PM2.5 and PM10, have 5 V power and a UART interface, so the basic connection is similar in every model.

How to connect Plantower sensors

You power the sensor with 5 V and read the data via the UART interface. Connect power and ground, and connect the sensor's TX line to the RX input of Arduino, ESP32 or Raspberry Pi. Before connecting, check the signal logic levels in the documentation and match them to your board. If needed, use a level converter.

You can receive the data from the serial port with your own code or with the help of a library. You can display the PM1.0, PM2.5 and PM10 results on a screen, save them in memory or send them to the network.

What you can use Plantower sensors for

You can choose sensors from the air quality sensors category for the following applications:

• air quality stations
• air purifiers
• DIY projects with Arduino, ESP32 and Raspberry Pi

Place the sensor so that air can flow freely through its inlet. Do not cover the openings with the enclosure or cables, because the measurement result may be unstable. In an outdoor station, provide protection against rain.
