The Tzone RS485 Temperature Sensor Modbus RTU Temperature and Humidity Transmitter is a precision industrial monitoring device designed for reliable environmental control in heating, cooling, agricultural, and greenhouse applications. It integrates a robust RS485 Modbus RTU communication interface with analog output, enabling seamless integration into building automation systems, PLC controllers, and data loggers. The sensor measures temperature from -40°C to 125°C with high accuracy, covering a wide operating range suitable for both extreme cold and hot environments. The humidity monitoring function provides additional environmental insight, making the unit a dual-purpose solution for comprehensive climate management.

Constructed with a durable polycarbonate housing, the transmitter withstands harsh industrial conditions, including dust, moisture, and temperature fluctuations. The internal circuit board features quality components for stable signal transmission and long-term reliability. The device offers selectable temperature units (Celsius or Fahrenheit) and supports standard Modbus commands for easy configuration.

The analog humidity output provides real-time data for visual indicators or auxiliary controllers. Its compact form factor and versatile mounting options allow simple installation in ducts, walls, or equipment enclosures. The transmitter delivers consistent performance under continuous operation, with low power consumption and minimal drift over time.

The RS485 bus supports multiple devices on a single network, reducing wiring complexity and installation costs. The unit's IP rating ensures protection against water ingress, ideal for humid environments like greenhouses, mushroom farms, or livestock facilities. The wide power supply range accommodates common industrial voltages, further simplifying deployment.

Application scenarios include HVAC systems, cold storage warehouses, server rooms, pharmaceutical storage areas, and agricultural climate control. The sensor's precise readings enable efficient energy management by allowing precise temperature and humidity regulation. Its competitive price point of $34.00 offers exceptional value for industrial-grade performance, making it an economical choice for both small-scale projects and large facility upgrades.
