• Available to purchase on Amazon UK, DE, NL, FR, IT, ES, BE
• Advanced breakout board for air quality, temperature, humidity, air pressure, sound and light
• Compatible with Raspberry Pi (0/2/3/4/Pico), Arduino, ESP8266, ESP32 and many others
• Uses high-quality digital sensors BME680, VEML6030 and SPH0645LM4H
• Code samples for ESPHome, Home Assistant, IFTTT, web servers, and IoT are available on our GitHub
• No soldering required! Available with pre-soldered header pins

Measure more than 10 variables including air quality, pressure, light and sound levels. The on-board processor handles sensor management and analysis, helping you build advanced applications faster.

Monitor and understand your environment at home, work or school. Our fully-functional demo code shows you how to view data, interact with web services, send to IoT cloud, and more.

• Choose from 3 header pin versions: pre-soldered (straight/right-angle), or unsoldered
• Miniature size: just 37.5 x 23.4 x 3.1 mm (without pins)
• Suitable for 3.3 V and 5.0 V systems
• I2C interface with selectable address
• Two interrupt outputs for fast host system alerts

Operating modes

The MS430 has two modes of operation, giving you flexibility and convenience:

• Standby mode: trigger single measurements when you want them.
• Cycle mode: sensor measurements repeat automatically. You can choose from 3, 100, or 300 seconds repeat interval.

Please note

• This product requires a host system (e.g. Arduino or Raspberry Pi) and connecting wires.
• Using the MS430 inside, or on top, of a Raspberry Pi case will increase the temperature reading, due to the heat output from the Pi.
• The gas sensor requires an initial period of "burn-in", and the air quality index requires an initial self-calibration period. Please see instructions for further details.
• The MS430 also provides an interface and data processing for the Nova SDS011 particle sensor, but this sensor is not included with the MS430 (can be purchased separately).
