GY-BME280-5V BME280 5V Digital Temperature Humidity Sensor High Precision Atmospheric Barometric Pressure Sensor Module Sensor Board with IIC I2C Breakout(Pack of 5PCS)

Features: 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. The board has selectable I2C address jumper (solder link GS2), I2C pull-up resistors, 7 pin header 2.54mm/ 0.1 inch, 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. Operating range -40~+85 ℃ 0-100 % rel. humidity; 300-1100 hPa Humidity sensor and pressure sensor can be independently enabled/disabled. This precision sensor is a 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. Applications:Humidity sensors and air pressure sensors can be independently enabled/disabled by configuring the sample rate register, the sample rate of the sensor can be set, ideal for mobile devices with limited space, such as smart phones, tablets, smart watches and wearables, weather forecasts, vertical speed indicators, flight control devices, indoor and outdoor navigation, smart home devices. Package include: 5 x GY-BME280-5V BME280 5V Digital Temperature Humidity Sensor

• 【Sensor Features】GY-BME280 is a digital composite sensor integrated temperature, humidity and barometric pressure module, can measure temperature humidity and pressure.
• 【Advantage】The humidity sensor has fast wake up and response time, high precision and wide temperature operating range; The pressure sensing element is a piezoresistive low noise, high precision and high resolution absolute atmospheric pressure sensing element. The temperature sensing element has the characteristics of low noise and high resolution, and the temperature value can be self-corrected by temperature compensation for humidity and air pressure.
• GY-BME280-5 use I2C and SPI (supports 3-wire , 4-wire SPI) interface. Interface: I2C (up to 3.4MHz); SPI (up to 10 MHz); The board has selectable I2C address jumper (solder link GS2), I2C pull-up resistors, 7 pin header 2.54mm/ 0.1 inch, and two mounting holes 3.5mm.
• 【Both I2C and SPI avilable】The BME280 sensor is great for all sorts of weather sensing and can even be used in both I2C and 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.
• 【precision sensing solution】BMP280 is a 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 good, you can also use it as an altimeter with ±1 meter accuracy.
