Description

The TSH202 is a 1-Wire Temperature and Humidity Sensor suitable for environmental monitoring. The 1-Wire interface delivers an accurate and cost-effective solution for environmental monitoring in a wide array of monitoring applications. The TSH202 integrates a capacitive humidity sensor with a band-gap temperature sensor, which connect to a 12-bit analogue to digital converter. This design ensures high signal quality, rapid response times, and dependable long-term operation. Furthermore, the sensor provides a fully calibrated digital output, streamlining its incorporation into various monitoring systems.

Each TSH202 sensor is equipped with a unique 64-bit serial code, enabling the seamless operation of multiple sensors on a single 1-Wire bus without the risk of interference or added complexity. This feature allows for flexible and scalable deployment in diverse settings, including food and drug storage, server rooms, building automation systems, and mobile operator sites, among other environmental monitoring scenarios. Consequently, it aids in maintaining consistent performance and supports adherence to regulatory standards, such as those set by authorities like the SFDA.
