CANABLOX® Temperature-Humidity-Pressure Sensor Module I2C (CX-BME280-S)

The CANABLOX® Temperature-Humidity-Pressure Sensor CX-BME280-S measures temperature (-40 to +85 °C, ±1 °C accuracy), humidity (0–100% RH, ±3% accuracy), and barometric pressure (300–1100 hPa, ±1 hPa accuracy). The combination of these 3 sensors in a single package makes it ideal for weather stations, indoor climate monitoring, altitude tracking, and IoT applications.

Selectable I2C address: 0x76, 0x77

Code example:
Download a demo sketch (tested with XIAO ESP32C6) that sends the measurements for temperature, humidity and pressure to the serial monitor.

Through-Hole (TH) connectors, like the I2C pin header or screw terminals, are included but not factory assembled.

The CANABLOX® ecosystem

CANABLOX® is a modular, clean, stackable ecosystem that replaces the chaos of traditional prototyping with I2C-connected building blocks.

CANABLOX® is not just a hobby tool; it’s a stepping stone from prototype to finished product. With over 60 modules envisioned, from environmental sensors to serial bridges and audio applications, CANABLOX® becomes a platform, not just a product.

Every CANABLOX® module connects directly to a sturdy baseplate or standardized cables, letting you build solid, real-world systems - without the clutter.

All modules use standardized CANABLOX® slot sizes and can be connected either through 4-pin JST-SH cables (compatible with Qwiic and Stemma QT) or by direct mounting onto the baseplate with headers. Every baseplate includes I2C headers (not assembled) and mounting hardware.
