Teracom TSP200 - 1-Wire barometric pressure sensor
TSP200 is a barometric pressure sensor with 1-Wire interface. Its basic silicon MEMS element is based on proven piezo-resistive pressure sensor technology featuring high EMC robustness, high accuracy and linearity and long term stability. A mixed-signal application-specific integrated circuit (ASIC) performs A/D conversions and provides the conversion results. The temperature measured by the internal temperature sensor is used for sensor specific compensation, using preset parameters.
The absolute barometric pressure sensor is a nano power and wide temperature range working device. This is essential, when focusing on low-power environmental monitoring applications.
TSP200 communicates over a 1-Wire bus. Each sensor has a unique 64-bit serial code. The 1-Wire absolute barometric pressure sensor utilizes two RJ11 connectors for easy daisy chain sensors wiring.
