FAQs

The GY-BME280 works with 3.3V and 5V microcontrollers like Arduino, Raspberry Pi, ESP32, and STM32. It uses I2C and SPI interfaces, making it easy to integrate into most DIY electronics and IoT projects.

Connect VCC to 3.3V or 5V, GND to ground, SCL to the I2C clock pin, and SDA to the I2C data pin. For SPI, use the labeled pins. Install the Bosch BME280 library in your IDE, then run a basic example sketch to read temperature, humidity, and pressure.

The package includes one GY-BME280 temperature, humidity, and atmospheric pressure sensor module. Jumper wires and microcontrollers are not included unless specified in the listing.

The module supports 3.3V to 5V input. It measures temperature from -40°C to 85°C with ±1°C accuracy, humidity from 0% to 100% RH with ±3% accuracy, and pressure from 300 hPa to 1100 hPa with ±1 hPa accuracy.

Yes, most sellers offer a 30-day return policy and a 12-month warranty against manufacturing defects. Check the specific product listing for exact warranty and return terms before purchase.

The sensor can measure outdoor conditions, but it should be protected from direct water, dust, and condensation. Use a weatherproof enclosure with a breathable membrane to maintain accurate humidity and pressure readings.
