EXD-AR20 is a Honeywell pressure/temperature/altitude module that provides reliable and accurate monitoring of pressure, temperature, and altitude data in a small, easy-to-install form factor. The module features a rugged enclosure, along with proprietary Honeywell ICM pressure and temperature sensors. The module is capable of measuring pressure from 1 to 30 mb, temperature from -40 Celsius to 85 Celsius, and altitude from 0 meters to 10,000 meters above sea level. The EXD-AR20 can also be interfaced with popular architectures including I2C, SPI, and UART.
