Are you looking for a small, accurate and power-saving Sensor for temperature, humidity and air pressure for the implementation of your SmartHome or a model project? Then you are exactly right here! With its high resolution and the low power consumption of these Sensor modules are Ideal for all Maker. Whether to support height determination for GPS, in the model, or as a weather station, through a universal Interface and common libraries for Arduino, Raspberry & Co. the application Is particularly comfortable. The Sensors were calibrated at the Bosch factory. There are different modes of operation to choose from, from ultra low power to ultra-high resolution (depending on the module). BME280, the precision sensor from , is soldered onto PCB. Not only the pressure and the temperature, this sensor can measure humidity. It uses both I2C and SPI (supports 3-, 4-wire SPI) interface Specifications: Supply Voltage: 3.3V DC Interface: I2C (up to 3.4MHz), SPI (up to 10 MHz) Operational Range: Temperature: -40 to +85°C Humidity: 0-100% Pressure: 300-1100 hPa Resolution: Temperature: 0.01°C Humidity: 0.008% Pressure: 0.18Pa Accuracy: Temperature: +-1°C Humidity: +-3% Pressure: +-1Pa I2C address SDO LOW : 0x76 SDO HIGH: 0x77 https://elecena.pl/product/17485412/gy-bme280-3v-environmental-sensor-module 2021-03-29 https://elecena.pl/product/17485412/gy-bme280-3v-environmental-sensor-module 2022-09-17
