GY-BME280-3.3 High Precision Barometric Pressure Module - Purple
ME-BME280 is a Breakout Board featuring a Bosch Sensortec ME280 Temperature£¬ Humidity & Pressure Sensor. The board has selectable I2C address jumper (solder link GS2)£¬ I2C pull-up resistors£¬ 7 pin header 2.54mm£¬ and two mounting holes 3.5mm. Default setting of the board; single power rail Vdd=Vdd_IO (solder link GS1)£¬ pull-ups resistors (R2£¬ R3) 10k£¬ protocol selector resistor 0ohm (R1)£¬ decoupling capacitors 0.1uF on both power supply pins Vdd & Vdd_IO. If you connect board to both power rails VDD_IO 1.8V and VDD 3.3V be sure to remove the power rail jumper GS1! BME280 Features - Package 2.5 mm x 2.5 mm x 0.93 mm metal lid LGA - Digital interface I2C (up to 3.4 MHz) and SPI (3 and 4 wire£¬ up to 10 MHz) - Supply voltage VDD main supply voltage range: 1.71 V to 3.6 V VDDIO interface voltage range: 1.2 V to 3.6 V - Current consumption 1.8 uA @ 1 Hz humidity and temperature 2.8 uA @ 1 Hz pressure and temperature 3.6 uA @ 1 Hz humidity£¬ pressure and temperature 0.1 uA in sleep mode - Operating range -40…+85 C£¬ 0…100 % rel. humidity£¬ 300…1100 hPa- Humidity sensor and pressure sensor can be independently enabled/disabled Bosch has stepped up their game with their new BMP280 sensor£¬ an environmental sensor with temperature£¬ barometric pressure that is the next generation upgrade to the BMP085/BMP180/BMP183. This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI! This precision sensor from Bosch is the best low-cost£¬ precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuraccy£¬ and temperature with ±1.0°C accuracy. Because pressure changes with altitude£¬ and the pressure measurements are so good£¬ you can also use it as an altimeter with ±1 meter accuracy The BME280 is the next-generation of sensors from Bosch£¬ and is the upgrade to the BMP085/BMP180/BMP183 - with a low altitude noise of 0.25m and the same fast conversion time. It has the same specifications£¬ but can use either I2C or SPI. For simple easy wiring£¬ go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions£¬ go with SPI.
