TSH202: 1-wire humidity and temperature sensors.

The TSH202 provides precise digital humidity and temperature measurements via a 1-Wire interface, offering 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 coupled to a 12-bit analog-to-digital converter. The sensing elements are factory calibrated, ensuring stable accuracy, fast response, and reliable 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, allowing 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, telecommunication sites, and general environmental monitoring. It also helps organizations maintain compliance with standard regulatory requirements in sectors such as food safety, pharmaceutical storage, and environmental control – including bodies like the FDA, SFDA, and other comparable regulatory bodies worldwide.
