Highly accurate I2C BME280 temperature + humidity + atmospheric pressure sensor offer a stable ultra low power platform for an environment sensory board.
Can be stacked directly with Moteino and MoteinoUSB (not on MoteinoMEGA). Onboard battery monitor from VIN, reading on A7, through a 2/3 (1MEG+2MEG resistor divider).
Unpopulated Si7021 pad allows soldering that sensor yourself if you'd like.
See the new WeatherShield Guide here!
IMPORTANT: To reduce idle current to ~1uA, the current batch comes with 1MEG+2MEG resistor divider on A7 (vs older 4.7k+10K)
What you get:
An example of reading values from this sensor board is posted in this RFM69 library example sketch. Also the MotionMote sample sketch illustrates reading the BME280 sensor.
For reference only - a sample WeatherShield R1 wireless sketch to read and send weather data (from Si7021 & BMP180) via RFM69 to a Moteino Gateway from this sensor is also available here.
