Modbus RTU temperature and humidity sensor - TSH331

Keeping industrial equipment and technical infrastructure operating reliably often requires continuous monitoring of environmental conditions. Temperature and humidity fluctuations can affect electronics, automation systems, and sensitive equipment, making dependable sensing an important part of modern industrial monitoring. The TSH331 IP54 temperature and humidity sensor provides accurate environmental measurements designed for integration into industrial automation and Modbus-based monitoring systems.

Manufactured by Teracom Ltd., a trusted developer of environmental monitoring and connectivity solutions, the TSH331 is built for stable long-term operation in demanding environments. The sensor combines a precision capacitive humidity sensing element with a bandgap temperature sensor. Internal electronics digitize both signals through a high-quality 12-bit analog-to-digital converter, ensuring consistent and repeatable measurements. With ±3.0% RH accuracy, 12-bit humidity resolution, and 14-bit temperature resolution, the device delivers reliable environmental data across a wide range of industrial and infrastructure applications.

Designed for easy integration, the sensor communicates via RS-485 using the widely adopted Modbus RTU protocol. It supports multi-drop RS-485 networks, allowing multiple sensors to operate on a single bus with individually assigned Modbus addresses - ideal for distributed monitoring in automation systems, telecom facilities, or technical infrastructure.

The IP54 enclosure protects the device against dust and water sprays, while the cable gland and screwless terminal block simplify wiring and speed up installation.

The TSH331 is compatible with:

• Industrial PLCs supporting Modbus RTU
• SCADA systems and automation controllers
• Teracom monitoring modules and controllers
• Building management systems (BMS)
