BMP280 Sensor Module
The BMP280 sensor is a small device that measures air pressure and temperature. It's designed for mobile phones and watches because it's tiny and doesn't use much power. You can use it to check the weather, navigate indoors or outdoors, and even monitor your health.
This BMP280 temperature pressure sensor is good at sensing weather changes and can be used with both I2C and SPI. It's made by Bosch and is a low-cost solution for measuring air pressure and temperature accurately. high temperature pressure sensor is a perfect solution for measuring barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy. Because pressure changes with the altitude and the pressure measurements are so good, you can also use this as an altimeter with ±1 meter accuracy.
The BMP280 barometric pressure sensor includes a selectable I2C address jumper (connected by solder link GS2), two mounting holes with a diameter of 3.5mm, I2C pull-up resistors, and a 7-pin header with a spacing of 2.54mm. This high accuracy barometric pressure sensor is an upgrade from older sensors like BMP085/BMP180/BMP183, with similar specs but improved performance.
You can choose I2C for simple wiring or SPI if you want to connect many sensors easily. Overall, the BMP 280 is a good choice for accurate and affordable pressure and temperature measurements.

1.What is BMP280 used for?
- BMP280 is a digital pressure sensor that is commonly used to measure atmospheric pressure and temperature. It is often used in applications such as weather forecasting, altitude measurement, and indoor air quality monitoring. It is a compact and low-power device that can be easily integrated into a wide range of systems and applications. The sensor is calibrated at the factory and is able to measure pressure over a range of 300 to 1100 hPa with a resolution of 0.01 hPa. It can also measure temperature over a range of -40 to 85°C with a resolution of 0.01°C.
2.What is a BMP280?
- BMP280 is a digital pressure sensor that is used to measure atmospheric pressure and temperature. It is a compact and low-power device that can be easily integrated into a wide range of systems and applications.The BMP280 operates by measuring the pressure and temperature of the air around it and outputting a digital signal that can be read by a microcontroller or other computer system. It is based on piezoresistive technology, which means that it uses a small change in resistance to measure the pressure applied to a diaphragm.
3.How does a BMP280 sensor work?
- The BMP280 is a digital pressure sensor that uses piezoresistive technology to measure pressure and temperature. It is an absolute barometric pressure sensor, meaning that it can measure the pressure of the air around it and output an accurate reading in units of pascals (Pa). The sensor works by measuring the resistance of a small, thin membrane called a diaphragm, which is located at the bottom of the sensor. When the pressure of the air around the sensor changes, the diaphragm is deformed slightly, causing a change in resistance. This change in resistance is then measured by the sensor and used to calculate the pressure. The BMP280 also has a temperature sensor built into it, which allows it to measure the temperature of the air around it in addition to the pressure. The sensor uses a thermistor to measure temperature, which is a type of resistor that changes resistance based on temperature.
4.What is the difference between BME280 and BMP280?
- The BME280 and BMP280 are both digital pressure and temperature sensors that use piezoresistive technology to measure these physical quantities. However, there are a few key differences between these two sensors:
- Humidity sensing: The BME280 includes an additional humidity sensor, which allows it to measure the relative humidity of the air in addition to pressure and temperature. The BMP280 does not have this capability.
- Package size: The BME280 is slightly larger than the BMP280, as it includes the additional humidity sensor.
- Sampling rate: The BME280 can sample at a higher rate than the BMP280, with a maximum rate of 20 samples per second compared to the BMP280's maximum of 10 samples per second.
- Operating range: The BME280 has a slightly wider operating range than the BMP280, with a temperature range of -40°C to +85°C compared to the BMP280's range of -40°C to +85°C.
