Adafruit BME280 I2C or SPI Temperature Humidity Pressure Sensor
We have ✅ 4 available of the AF-2652 in our Sydney warehouse. An extra 100 units available with a short lead time.
The Adafruit BME280 Breakout is a precision environmental sensor from Bosch that measures temperature, barometric pressure, and humidity in a single package. With its excellent pressure accuracy, it also functions as an altimeter with approximately ±1 metre resolution.
The breakout includes a 3.3V regulator and level shifting, so it works with both 3V and 5V microcontrollers. It supports both I2C and SPI interfaces — use I2C for simple two-wire connections, or SPI to avoid address collisions when connecting multiple sensors.
