Common Questions
Which I2C sensor is best for a weather station?
BME280 is a common starting point when pressure matters; AHT20 or SHT30 can be better when humidity and temperature are the core need.
Can I mix multiple I2C sensors on one board?
Yes, if addresses do not conflict and pull-ups are appropriate. Use an I2C multiplexer when duplicate addresses cannot be changed.
