Multi-Sensor Stick (BME280 + LTR559 + LSM6DS3)

by Pimoroni

A 3-in-1 super sensor suite for environmental, light and movement sensing, with Qw/ST for easy, solderless connectivity.

We heard you like sensors (we definitely like sensors!). So we combined three of our favourite ones into a convenient, small, stick-shaped format that's perfect for adding additional smarts to a bunch of different projects. The onboard I2C sensors can detect:

  • Temperature 🌞
  • Pressure ☔
  • Humidity 💧
  • Light 💡
  • Proximity ✋
  • Orientation 🙃
  • Motion (including steps, single and double taps and freefall 🍃)

It has a Qw/ST (also known as STEMMA QT and Qwiic) connector at each end to make it easy to connect it up to Qw/ST compatible microcontrollers, HATs and other boards via cable. Qw/ST cables are sold separately.

Software

If you're planning on using the Multi-Sensor Stick with Raspberry Pi Pico (or another RP2040/RP2350 microcontroller) there are drivers for BME280 and LTR559 baked into our custom MicroPython builds. We've spun up a new standalone MicroPython library for LSM6DS3 - search for lsm6ds3-micropython in Thonny's 'Manage Packages' to install it.

There's also full-fat Python libraries for if you're using a Raspberry Pi computer:

Notes

  • Dimensions: 52x7.9x4.2mm (LxWxH, including connectors). The mounting holes are M2.5.
