BME 280 sensor module - temperature, humidity and pressure. Simple to use temperature, humidity and pressure sensor. Successor to the BMP180 sensor. It communicates via the I2C or SPI interface. It is used, among others for weather stations, controlling room conditions. Specification: Measurement range (full accuracy): Pressure: 300 - 1100 hPa Temperature: -40 - 85C System interfaces: I2C and SPI Average energy consumption for measurements every 1s: 1.8 (humidity, temperature) 2.8 (pressure, temperature) 3.6 (humidity, pressure, temperature) Average power consumption in sleep mode: 0.1 Humidity sensor: Response time (63%): 1s Accuracy: 3% relative humidity Hysteresis: ¤ 2% Pressure sensor: RMS Noise: 0.2 Pa (corresponds to 1.7 cm) Measurement error: 0.25% (corresponds to 1 m for 400 m of altitude change) Temperature coefficient shift: 1.5 Pa / K (corresponds to 12.6 cm at 1 ° C temperature change) Technical data: Supply voltage: 3.3V Size: 15 x 10 mm Weight: 1 g Mounting holes diameter: 3 mm Pinout: VCC - Supply voltage 3.3V GND - Ground SCL - I2C / SPI clock SDA - I2C / MOSI data line in SPI mode CSB - Chip Select SD0 - MISO in SPI mode https://elecena.pl/product/22604903/bme280-temperature-humidity-and-pressure-sensor-3-3v-arduino 2023-02-22 https://elecena.pl/product/22604903/bme280-temperature-humidity-and-pressure-sensor-3-3v-arduino 2024-02-03 https://elecena.pl/product/22604903/bme280-temperature-humidity-and-pressure-sensor-3-3v-arduino 2025-06-09 https://elecena.pl/product/22604903/bme280-temperature-humidity-and-pressure-sensor-3-3v-arduino 2025-10-25 https://elecena.pl/product/22604903/bme280-temperature-humidity-and-pressure-sensor-3-3v-arduino 2025-10-29
