Frequently Asked Questions

What is the operating voltage range for the 7Semi BME280 module?

The module's core sensor (VDD) operates from 1.71V to 3.6V. The I/O voltage (VDDIO) can be independently supplied from 1.2V to 3.6V, allowing flexible interfacing with both 3.3V and 5V logic microcontrollers using appropriate level shifting if necessary.

How do I select between I2C and SPI communication interfaces?

The interface is selected via the CSB (Chip Select) pin. Pulling CSB high (to VDDIO) enables the I2C interface. Pulling CSB low enables the SPI interface. The module's breakout header provides access to all necessary pins for both protocols.

What is the typical accuracy for humidity and pressure measurements?

The humidity accuracy is ±3% RH across the full 0-100% range. The absolute pressure accuracy is ±1.0 hPa within the 0°C to 65°C temperature range. For relative pressure changes, the sensor offers high precision with ±0.12 hPa relative accuracy.

Can this sensor be used for altitude measurement?

Yes, the BME280's precise barometric pressure measurement (300-1100 hPa range) can be used to calculate altitude changes based on the barometric formula. It is suitable for applications like drone altimeters, hiking GPS units, and weather balloon payloads.

What is the purpose of the different operating modes (Sleep, Forced, Normal)?

Sleep mode minimizes power to 0.1 µA. Forced mode takes a single measurement then returns to sleep, ideal for battery-saving periodic sampling. Normal mode continuously cycles measurements at a configurable standby interval, providing constant data for real-time monitoring.
