Frequently Asked Questions

What is the operating voltage for the Crowtail BME280 module?

The sensor core operates at 3.3V DC. However, the I2C communication lines are 5V-tolerant, meaning you can power the module from a 3.3V source while communicating with a 5V microcontroller like an Arduino Uno without risk of damage, thanks to onboard level shifting.

How do I connect this sensor to an Arduino or Raspberry Pi?

Connect the module using the included 4-pin Crowtail cable to a compatible Crowtail base shield, which breaks out to standard headers. For direct wiring, connect VCC to 3.3V, GND to ground, SDA to the I2C data line, and SCL to the I2C clock line on your microcontroller. The I2C address is typically 0x76 or 0x77.

What is the accuracy and measurement rate of this sensor?

The Bosch BME280 provides a relative pressure accuracy of ±12 Pa and humidity accuracy of ±3% RH between 20-80%. The measurement rate is configurable via software, supporting standard and high-performance modes to balance data resolution with power consumption for your specific application.

Can this sensor be used for altitude measurement?

Yes, the barometric pressure reading can be converted to altitude with a relative accuracy of approximately ±1 meter at SEA level and ±2 meters at 30,000 feet (9.2 km). Accurate altitude tracking requires a known reference SEA-level pressure for calibration.
