Additional Details
The ZS-RTU-TTL is an industrial-grade digital temperature and humidity data acquisition module designed to connect multipoint 1-Wire sensor networks with TTL-level serial communication systems.
The module collects measurement data from up to 200 digital temperature sensors, including DS18B20 and compatible sensor variants, as well as supported 1-Wire temperature and humidity sensors. It converts, sorts, and organizes sensor readings into structured serial data that can be accessed by microcontrollers, embedded controllers, and other compatible host devices.
Supporting extension cable lengths of up to 1,500 meters, the ZS-RTU-TTL is designed for distributed temperature monitoring applications requiring long-distance communication and high sensor capacity.
The module supports both Modbus RTU and a proprietary ASCII communication protocol. Its built-in automatic sorting function organizes sensor readings into predictable Modbus register addresses, reducing the complexity of host-side software integration.
The custom ASCII protocol provides additional functionality for sensor discovery, identification, configuration, and temperature data retrieval.
Selectable 9,600 and 115,200 bps baud rates provide flexibility for different host systems, while an integrated watchdog automatically restarts the module following an unexpected system lockup.
Designed for embedded integration, the ZS-RTU-TTL features compact dimensions, configurable operating parameters, and isolated sensor-side circuitry to support reliable operation in industrial monitoring environments.
