1-Wire humidity and temperature sensor TSH202
Description
TSH202 provides accurate, digital environmental measurements over a 1-Wire interface, making it ideal for reliable and cost-effective monitoring across diverse applications
It combines a capacitive humidity sensor with a band-gap temperature sensor, both linked to a 12-bit analog-to-digital converter. As a result, it ensures excellent signal quality, fast response times, and reliable long-term performance. Additionally, the sensor provides a fully calibrated digital output, simplifying integration into various monitoring systems.
Moreover, each TSH202 features a unique 64-bit serial code, so multiple sensors can easily operate on the same 1-Wire bus without interference or complexity.
This allows flexible and scalable deployment in applications such as food and drug storage, server rooms, building automation systems, mobile operator sites, and other environmental monitoring scenarios. Above all, it helps ensure consistent performance and supports compliance with regulatory requirements, including those from authorities like SFDA.
