Description

The TSP200 is a 1-Wire ambient pressure sensor designed for accurate and stable atmospheric pressure measurements. It’s built around a robust silicon MEMS element, which utilises proven piezo-resistive pressure sensor technology. This foundation ensures high accuracy, excellent linearity, and long-term stability, making it reliable for various applications. An integrated mixed-signal application-specific integrated circuit (ASIC) handles analogue to digital conversions, while an internal temperature sensor provides data for precise, sensor specific compensation.

This absolute barometric pressure sensor is distinguished by its nano-power consumption and ability to operate across a wide temperature range, making it particularly suitable for low-power environmental monitoring applications. The TSP200 communicates via a 1-Wire bus, with each sensor possessing a unique 64-bit serial code for individual identification in multi-sensor setups. For ease of installation and wiring, it features two RJ11 connectors, facilitating convenient daisy-chain configurations.
