1-Wire humidity and temperature sensor TSH202

TSH202 is a 1-Wire humidity and temperature sensor with IP00 protection.

Description

TSH202 delivers precise digital measurements of humidity and temperature through a 1-Wire interface, providing a reliable and cost-effective solution for a wide range of environmental monitoring applications.

Inside the device, a capacitive humidity element and a band-gap temperature sensor are paired with a 12-bit analog-to-digital converter. The sensing elements are factory-calibrated, ensuring stable accuracy, fast response, and dependable long-term performance. The fully digital output simplifies integration and minimizes the need for additional calibration or signal conditioning hardware.

Each TSH202 also includes a unique 64-bit serial code, enabling multiple sensors to operate on the same 1-Wire bus without conflicts or complex addressing.

This design supports flexible and scalable deployment in food and drug storage, server rooms, building automation, telecom sites, and general environmental monitoring. It also helps organizations maintain compliance with common regulatory expectations in sectors such as food safety, pharmaceutical storage, and environmental control – including authorities such as FDA, SFDA, and other comparable regulatory bodies worldwide.
