Product Description


1. UPGRADED - Better than BMP085/BMP180/BMP183, great for all sorts of weather sensing.
2. HIGH PRECISION - Barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0 °C accuracy.
3. LOW POWER CONSUMPTION - Low power consumption of 2.7µA.
4. 3.3V VOLTAGE STABILIZING CIRCUIT - With 3.3V voltage regulator tube for a 5V or 3.3V power.
5. I2C OR SPI INTERFACE - I2C: easy wiring; SPI: free of port conflict worry.

The BMP280 is an absolute barometric pressure sensor especially designed for mobile applications. The sensor module is housed in an extremely compact 8-pin metal-lid LGA package with a dimension of 2.0 x 2.5 x 0.95m. Its small dimensions and low power consumption of 2.7µA@1Hz allow the implementation in battery-driven devices such as mobile phones, GPS modules or watches. With the I2C and SPI communication, you can apply it in different uses. It's a best choice for experiments like testing altitude and some projects involving air pressure.

Really good sensor and company By Andyk1 2018-05-17 18:04:58

Got this from China in about a week and wasn't expecting it for a month or more. Had a problem right off the bat but turned out it was my software writing skills and not the sensor. Tricky to program if your not a code writer. There are a lot of places to find software examples and some work and some don't. Adafruit's BME280 seems about the best and alot of your own modifications if you choice. Googling helps a lot.All in all I am very happy with this sensor and company. Quick response to emails and support

Works great! By Craig S. 2018-05-17 17:28:02

"Works great! I connected it to the I2C channel of a Raspberry Pi and, using the data sheet I found on the chip manufacturer's site, I wrote Python code to read the data and calibration values from the chip. I'm uploading video CWOP to MADIS, and the results are passing the MADIS quality check.
