TE Connectivity - Wireless sensor development board reports diverse variables (WPP100B001)

TE Connectivity (TE) 's MEAS wireless sensor development board. The board reports relative humidity, temperature, and atmospheric pressure via a Bluetooth 4.0 connection, providing environmental data for evaluating weather stations, HVAC systems, and other industrial applications. The development board is for demonstration or evaluation purposes only. It has not been tested to comply with any FCC certification, and TE believes it is not a final product suitable for general consumer use. The evaluation board is based on two MEAS low-power sensors: the HTU21D (F) digital humidity sensor with temperature output and the MS5637 miniature altimeter. The HTU21D (F) sensor provides a calibrated linear signal to detect 0% to 100% relative humidity and 20 to +85 degrees Celsius. The MS5637 micro-altimeter is based on MEMS technology and includes a high linearity pressure sensor and an ultra-low power analog-to-digital converter (ADC) with internal factory calibration coefficients. The MS5637 sensor provides a barometric pressure reading of 300 to 1,200 mBar. There are two versions. 1-WPP100B001 version enables engineers to use the board with smartphones and tablets running the free TE Sensor Tag application, which can be downloaded from the Google Play Store for Android or the App Store for iOS. With a free application, engineers can use a smartphone or tablet as a circuit board display or data logging terminal. 2-The WPP109B001 version includes a USB dongle that connects the board to a computer running Windows, allowing engineers to use the software provided to access the board's functions.
