BME280 Temperature, Humidity and Pressure Sensor and Sonoff Basic with Tasmota - seurat-atreides/Sonoff-Tasmota GitHub Wiki
"BME280 sensor, an environmental sensor with temperature, barometric pressure and humidity", see Datasheet.
Connect BME280 to Sonoff-Basic based on the GPIO locations
- BME280-3.3V -> Sonoff-3.3V
- BME280-GND -> Sonoff-GND
- BME280-SCL -> Sonoff-TX
- BME280-SDA -> Sonoff-RX
NOTE:
YOU NEED TO DISABLE SERIAL LOG COMPLETLY TO ALLOW SENSORS ON TX/RX PINS
On Tasmota web interface go to „Configuration->Configure Module“ and set
Make sure I2C sensor is enabled before compiling:
// -- I2C sensors ---------------------------------
#define USE_I2C // I2C using library wire (+10k code, 0k2 mem, 124 iram)
#ifdef USE_I2C
#define USE_BMP // Enable BMP085/BMP180/BMP280/BME280 sensor (I2C address 0x76 or 0x77) (+4k code)
