SunFounder High Precision BMP280 Barometric Pressure Temperature Altitude Sensor Module

Features
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.

Product Description

Details

Introduction
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 10:04:58

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 09:28:02

"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.
