POZOR verze 5V. Vhodné pro Arduino UNO, Arduino NANO, Arduino MEGA a další desky Arduino nebo mikrokontroléry, které pracují na 5V.
GY-BME280 je Breakout Board s Bosch Sensortec ME280 senzorem teploty, vlhkosti a tlaku vzduchu.
- I2C pull-up rezistory
- Včetně 4pinového headeru 2.54mm
Vlastnosti BME280
- Značka senzoru: Bosch
- Rozměr senzoru 2.5mm x 2.5mm x 0.93mm kovové pouzdro LGA
- Digitální rozhraní I2C (až 3.4 MHz) a SPI (3 a 4 vodiče, až 10 MHz)
- Napájecí napětí: 5V
- Spotřeba proudu 1.8 uA @ 1Hz vlhkost a teplota, 2.8 uA @ 1Hz tlak a teplota. 3.6 uA @ 1Hz vlhkost, tlak a teplota a 0.1 uA v režimu spánku
- Rozsah teplotního senzoru -40 / +85 C,
- Rozsah vlhkosti; 0 - 100% rel. vlhkost
- Rozsah tlaku vzduchu: 300- 1100 hPa
- I2C
Takto připojíš 3v1 senzor Teplota Vlhkost a Tlak | 5V | I2C | Bosch BME280 k Arduino UNO nebo ESP32, s ukázkovým sketchem, který můžeš hned nahrát.
Tento projekt měří teplotu, relativní vlhkost a barometrický tlak pomocí snímače BME280 přes I2C. Naměřené hodnoty prostředí se vypisují do Serial Monitoru každé dvě sekundy. Stačí připojit snímač přímo k pinům 5V, GND a I2C na Arduino Uno.
