This Wireling lets you measure Humidity, Pressure, Temperature, and the approximate Altitude all from the small BME280 sensor. This sensor is an upgrade from the BMP280 used on our Barometric Pressure TinyShield because it also includes a Humidity Sensor. Note* 5-Pin Wireling cables not included and sold separately.

    Bosch BME280 Sensor Specs

      TinyDuino Power Requirements

      • Voltage: 3.0V - 5.5V 
      • Current:
        • 1.8 µA @ 1 Hz humidity and temperature
        • 2.8 µA @ 1 Hz pressure and temperature
        • 3.6 µA @ 1 Hz humidity, pressure, and temperature
        • 0.1 µA in sleep mode

      Pins Used

      • A5/SCL - I²C Serial Clock line
      • A4/SDA - I²C Serial Data line

      Dimensions

      • 10mm x 10mm (.394 inches x .394 inches)
      • Max Height (from the lower bottom of Wireling to upper top Wireling Connector): 3.70mm (0.15 inches)
      • Weight: 1 gram (.04 ounces)
      • You can also use this Wireling without the TinyDuino – modifying the connecting cable by removing the opposite connector and stripping/tinning the wires, you can solder the connector cable to any other microcontroller board of your choice!
