Description

3In1 BME280 I2C SPI 3.3V Digital Sensor Temperature Humidity Barometric Pressure Sensor Module

BME280

Give your next project the ability to sense the world around it with the BME280. These sensors are fairly simple to use, pre-calibrated and don’t require extra components so you can start measuring relative humidity, temperature, barometric pressure & approx. altitude in no time.
With this small yet powerful device create your own weather station for your home automation.

PIN Connections:
To use SPI communication protocol, use the following pins:
  • SCK – this is the SPI Clock pin
  • SDO – MISO
  • SDI – MOSI
  • CS – Chip Select
To use I2C communication protocol, use the following pins:
  • SCK – this is also the SCL pin
  • SDI – this is also the SDA pin

Package includes:
1x BME280 3V

Please Note:
This Module needs the header pins soldered
