Datasheet

The Measurement Specialties Grove system development boards from TE Connectivity (TE) are now being shipped by Mouser Electronics. These small, plug-and-play development boards allow designers to incorporate TE’s environmental sensors with the Seeed Grove prototyping system, which features standardised four-pin connectors with an I²C communication interface.

The easy-to-use boards are ideal for creating designs for wearable and miniature devices, health monitoring, fitness, air quality, aerospace, and battery-powered applications.

The boarda are available in five options for sensing a combination of pressure, humidity, and temperature. The HTU21D board includes a fully calibrated humidity and temperature sensor that measures 0 to 100% relative humidity (RH) and minus 40 to 125 degrees Celsius (C).

The sensor also features selectable resolution, low battery detection, checksum capability, and a low-power standby mode for power-sensitive applications.

The MS5637 board is a self-contained pressure and temperature sensor specified for 300 to 1,200mbar and minus 40 to 85 degrees C.

The MS8607 board senses RH (0 to 100%) and pressure (300 to 1,200mbar) and adds temperature sensing in a range of minus 40 to 125 degrees C.

It also features selectable resolution for pressure, humidity, and temperature sensing.

For dedicated temperature sensing, TE offers two Grove system boards.

The TSYS01 board provides accuracy down to 0.1 degree in the minus 5 to 50 degrees C range, and 0.5 degrees in the full minus 40 to 125 degrees C range.

The TSYS02D board provides accuracy of 0.2 degrees C in the minus 5 to 50 degrees C range, 0.5 degrees in the minus 20 to 100 degrees C range, and 1.0 degree in the full minus 40 to 125 degrees C range.

Both the TSYS01 and TSYS02D offer a low-power standby mode for power-

sensitive applications.
