In a stint of list-o-mania TE Connectivity have slapped five environmental sensors on a single board called MEAS for plugging onto the Arduino/Genuino 101 and Uno R3. Here goes in telegram style:

>HI DONALD
  1. HTU21D self-contained humidity and temperature sensor with selectable resolution. RH from 0 to 100 percent and T from –40 to 125 degrees C.
  2. MS5637 high-linearity pressure sensor for 300 mbar to 1200 mbar, plus an ultra-low power 24 bit ADC with internal factory-calibrated coefficients.
  3. TSYS01 covers –40 to 125 degrees C at 0.1 to 0.5 degrees accuracy with a 24-bit ADC.
  4. MS8607 combined pressure, humidity and temperature sensor with extended pressure range of 10 to 2000 mbar.
  5. TSD305-1C55 contactless temperature measurement system with thermopile infrared sensor and a sensor signal conditioner. Covers 0 to +100 degrees C at ±1 degree accuracy.
The MEAS board offers a 64-pad prototyping area for soldering external devices and Arduino/Genuino-compatible headers for I2C communication. The “all-weather board” is available from Mouser.
