Raspberry Pi

Single-board computer (Linux)

Released 2012

Not a microcontroller: it's a full Linux computer. For the Python crowd, a short script reads the sensors and sends them — runs on any Pi with a network, from the Zero 2 W to the Pi 5.

Processor Broadcom ARM (Cortex-A53/A72/A76, varies by model)

Clock 1.0 GHz (Zero 2 W) to 2.4 GHz (Pi 5)

Memory 512 MB to 8 GB RAM · microSD card

Connectivity WiFi + Bluetooth + Ethernet (varies by model)

GPIO 40-pin header · no native ADC

Logic level 3.3 V (GPIO)

Programmed in Python 3 (or any language — full Linux)

💡

Good to know No native ADC — for analog sensors add an ADS1115 (I²C).

Sensors that pair well

Air temperature Air humidity CO₂ Distance Current (non-invasive AC)
