The Sensirion SPS30 is a compact, high-quality optical particle sensor that uses laser scattering and Sensirion's innovative contamination-resistance technology for superior binning and particle measurement. It measures both mass concentration and particle count across PM1.0, PM2.5, PM4.0, and PM10 size bins.
With a compact form factor of just 41 × 41 × 12 mm, a sensor lifetime of over 8 years, and a built-in self-cleaning procedure, the SPS30 is ideal for long-term deployments in difficult-to-access locations. An included 5-pin cable with breadboard-friendly, colour-coded wires makes hookup straightforward.
Key Features
- Multi-Bin Particle Measurement – Measures PM1.0, PM2.5, PM4.0, and PM10 mass concentration and particle count
- Dual Interface – Communicates over UART or I2C (5-pin connector)
- 5V Power, 3.3V/5V Logic – Works with both 3.3V and 5V microcontrollers
- Long Lifetime – Over 8 years of operation with built-in self-cleaning
- Compact – Just 41 × 41 × 12 mm
- Contamination Resistant – Sensirion's patented technology for reliable long-term readings
Ideal For
- Air quality monitoring stations
- Environmental sensing projects
- HVAC and ventilation systems
- Long-term outdoor deployments
Package Contents
- 1× Sensirion SPS30 Particulate Matter Sensor
- 1× 5-Pin Breakout Cable (1.5 mm connector to breadboard-friendly wires)
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- particulate matter
- Particulate matter means tiny particles suspended in the air, such as dust, smoke, pollen, or pollution. A sensor that measures it is useful for air-quality projects because particle levels can affect comfort and health.
- PM1.0
- PM1.0 refers to airborne particles with a diameter of about 1 micrometre or smaller. This size category matters because smaller particles can stay airborne longer and may come from sources such as smoke or combustion.
- PM10
- PM10 refers to airborne particles with a diameter of about 10 micrometres or smaller. It includes larger dust and pollen-like particles, so it is useful for detecting coarser airborne pollution.
- PM2.5
- PM2.5 refers to airborne particles with a diameter of about 2.5 micrometres or smaller. It is a common air-quality measurement because these fine particles can be breathed deep into the lungs.
- PM4
- PM4 refers to airborne particles with a diameter of about 4 micrometres or smaller. It gives another particle-size category, which can help compare different dust, smoke, or indoor pollution sources.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
