1-Wire barometric pressure sensor TSP200
The TSP200 is a 1-Wire barometric pressure sensor that employs silicon MEMS technology based on piezo-resistive pressure sensor principles. It offers exceptional EMC robustness, high accuracy, linearity, and long-term stability. An application-specific integrated circuit (ASIC) handles A/D conversions and utilizes internally measured temperature for sensor-specific compensation.
This absolute barometric pressure sensor operates within a wide temperature range and features nano power consumption, making it ideal for low-power environmental monitoring applications. The TSP200 communicates via a 1-Wire bus, with each sensor possessing a unique 64-bit serial code.
Two RJ11 connectors facilitate easy daisy-chaining of multiple sensors.
