Can BMP280 measure humidity?

The BMP280 can only measure temperature and air pressure, while the BME280 can measure humidity in addition to temperature and air pressure.

How accurate is BME280?

Once the BME280 is calibrated, you can expect a typical temperature accuracy of ±1.0°C. The datasheet (look at page 12) becomes as bad as ±1.25°C for temperatures towards the edges of its useful range. It gets even worse (±1.5°C) towards the edges of its operating range of -40°C to -60°C.

What is a BMP280?

The BMP280 is an absolute barometric pressure sensor, which is especially feasible for mobile applications. Its small dimensions and its low power consumption allow for the implementation in battery-powered devices such as mobile phones, GPS modules or watches.

How accurate is DHT22?

Also the DHT22 sensor has better humidity measuring range, from 0 to 100% with 2-5% accuracy, while the DHT11 humidity range is from 20 to 80% with 5% accuracy.

What is BMP180 sensor?

The BMP180 is the new digital barometric pressure sensor of Bosch Sensortec, with a very high performance, which enables applications in advanced mobile devices, such as smart phones, tablet PCs and sports devices.

How do you use a BMP280?

The following pins should be used:

  1. Connect Vin to the power supply, 3V or 5V is fine.
  2. Connect GND to common power/data ground.
  3. Connect the SCK pin to Digital #13 but any pin can be used later.
  4. Connect the SDO pin to Digital #12 but any pin can be used later.
  5. Connect the SDI pin to Digital #11 but any pin can be used later.

What is the ideal humidity in a house?

between 30-50% humidity
The ideal relative humidity for health and comfort is somewhere between 30-50% humidity, according to the Mayo Clinic. This means that the air holds between 30-50% of the maximum amount of moisture it can contain.
