HW-611 BMP280 3.3V Digital Barometric Pressure Altitude Sensor cukup mudah digunakan, telah dikalibrasi sebelumnya dan tidak memerlukan komponen tambahan. Anda cukup mulai mengukur kelembaban relatif, suhu, tekanan barometrik & kira-kira. ketinggian dalam waktu singkat.
Features of BME280 1. Interface: I2C & SPI 2. Supply Voltage: 1.71V to 3.6V 3. Temperature Range: -40 to +85°C 4. Humidity Range: 0% to 100% rel. humidity 5. Pressure Range: 300hPa to 1100hPa 6. Humidity sensor and pressure sensor can be independently enabled/disabled
Applications 1. Context awareness, e.g. skin detection, room change detection 2. Health monitoring/well-being 3. Home automation control 4. Control heating, ventilation, air conditioning (HVAC) 5. Internet of things 6. GPS enhancement & Indoor/Outdoor navigation 7. Weather forecast 8. Vertical velocity indication (rise/sink speed)
Pinout The BME280 I2C interface uses the following pins: 1. VCC: 1.71V to 3.6V 2. GND: Connect to GND 3. SCL: serial clock (SCK) 4. SDA: Serial data (SDI) 5. CSB: Must be connected to VDDIO to select I2C interface. 6. SDO: The I2C address decides the pin. If SDO connects to GND(0), the address is 0x76, if it connects to VDDIO(1), the address is 0x77. In this module, we have connected it to VDDIO, so the address should be 0x77.
