BMP280 barometric pressure sensor module CJMCU is easy to use with Arduino projects for precise reading of temperature or barometric pressure.
This is an environmental sensor with the ability to read temperature or barometric pressure. The sensor is ideal for projects requiring various information and data related to weather and is all too easy to use by both I2C and SPI through.
Sensor accuracy is one of the best all accessible sensors that can measure the pressure with an accuracy of ± 1hPa and temperature with an accuracy of ± 1.0 ° C. As the pressure changes with altitude, it can be used as a sensor for altitude with accuracy of ± 1 meter.
The new sensor is an upgrade sensor BMP280 BMP085 / BMP180 / BMP183, noise and altitude reduced to 0.25M while quickly converting. It has the same specifications, but can be used by both I2C and SPI through.
It is easy to use, the sensor SMD (surface-mount sensor) is glued to the PCB that has a 3.3V voltage regulator and a level shifting to be used with any 3V or 5V logic microprocessor.
