Review: “Reliable RS-485 sensor for Modbus-based monitoring (lab + OT pipeline tested)” - I’m using this sensor in a Modbus-based OT lab setup, so reliability and consistency matter more than just “it works.” Current setup: RS-485 sensor → Modbus → Python → JSON → InfluxDB → Grafana What’s working well: • Stable Modbus communication (no random drops under normal conditions) • Clean register reads — easy to parse and scale values in Python • Consistent temperature output (no jitter or unexpected spikes) • Works well with USB-to-RS485 adapters on Linux systems I’m polling it continuously as part of a monitoring pipeline, and it integrates cleanly into real-time dashboards. One important thing to know: • Like most Modbus devices, error handling matters — if communication drops, you need logic to detect stale or invalid data (not a sensor issue, but important for real systems) Big takeaway: This sensor is solid for building real monitoring pipelines, especially if you’re working with Modbus, SCADA-style systems, or industrial data collection. It’s not just a sensor — it’s a reliable data source for automation and detection workflows. Review: Very low quality sensor - This sensor is very slow when it works. I compared this with a Modbus RTU AM2320 and the response of the AM2320 is much faster. This sensor takes around 60 seconds or more to update the value. It is almost impossible to make a control. In most cases, it disconnects from the master and never answers back again. I tested with Modbus Poll and PLC. With Modbus Poll, I can see the messages from the master to this device and they look as they are supposed to be, however, the sensor doesn't answer back to the master. Very poor performance for the hight cost compared to cheaper ones. I will investigate if I can return this thing. ## Features - RS485 TEMPERATURE HUMIDITY TRANSMITTER: The industrial temperature sensor uses the newly designed CMOS chip SHT3X sensor, makes its performance more stable in high humidity environments; IP65 waterproof - MODBUS TEMPERATURE SENSOR WITH DIP SWITCH: The DIP switch is used to set the address to facilitate sensor identification; Supports simultaneous monitoring of multiple temp humidity sensors through computers or other monitoring devices - MEASUREMENT RANGE: Temperature measuring range is -40℉ to 257℉ (-40℃ to 125℃); humidity measuring range is 5% to 95% RH; DC:5 to 12V; Transmission rate(optional):4800 bps / 9600 bps / 19200 bps - MODBUS RTU TEMPERATURE SENSOR: This analog temperature sensor adopts RS485 communication interface output,compatible with the standard Modbus-RTU protocol; Fully calibrated and has the characteristics of good versatility, long transmission distance - COMPACT AND EASY TO USE: Low power consumption and strong resistance to chemical pollution; Small size, light weight, easy to carry and install, does not take up much space - WIDE APPLICATIONS: The temperature and humidity transmitter probe is ideal for industrial, HVAC, communication room, warehouse buildings, and automatic control applications ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CP7PLP6C | | Best Sellers Rank | #74,881 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #101 in Temperature Probes & Sensors | | Brand | Tzone | | Brand Name | Tzone | | Color | Gray | | Customer Reviews | 3.6 out of 5 stars 9 Reviews | | Item Type Name | RS485 temperature humidity transmitter | | Manufacturer | Tzone | | Model | THT02 | | Number of Items | 1 | | Part Number | THT02 | | Temperature Accuracy | 0.2 degrees_celsius | | Temperature Reading Accuracy | plus_minus_0_point_2_degrees_celsius | | Upper Temperature Range | 125 Degrees Celsius | | Upper Temperature Rating | 125 Degrees Celsius | ## Product Details - **Color:** Gray - **Brand:** Tzone - **Upper Temperature Rating:** 125 Degrees Celsius - **Temperature Accuracy:** 0.2 degrees_celsius - **Temperature Reading Accuracy:** plus_minus_0_point_2_degrees_celsius ## Images ![Tzone RS485 Temperature Sensor Modbus RTU Temp Humidity Transmitter Analog - Image 1](https://m.media-amazon.com/images/I/51ZQPaEwuuL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ “Reliable RS-485 sensor for Modbus-based monitoring (lab + OT pipeline tested)” *by J***S on April 5, 2026* I’m using this sensor in a Modbus-based OT lab setup, so reliability and consistency matter more than just “it works.” Current setup: RS-485 sensor → Modbus → Python → JSON → InfluxDB → Grafana What’s working well: • Stable Modbus communication (no random drops under normal conditions) • Clean register reads — easy to parse and scale values in Python • Consistent temperature output (no jitter or unexpected spikes) • Works well with USB-to-RS485 adapters on Linux systems I’m polling it continuously as part of a monitoring pipeline, and it integrates cleanly into real-time dashboards.

I'm using it to monitor the temperature in a freezer via a RS485 modbus over ethernet controller connected to HomeAssistant. So far it's working perfectly, and is more reliable than a wireless ESP32 based sensor. I'm extremely pleased with this sensor and would definitely recommend it! ## Frequently Bought Together - Tzone RS485 Temperature Sensor Modbus RTU Temperature and Humidity Transmitter,Industrial Temp Sensor Analog Humidity Monitor -40℃ to 125℃ High Accuracy for Heating and Cooling System,Farm,Greenhouse - PUSR TCP232-306 RS232 RS485 RS422 to Ethernet TCP IP Modbus Gateway Serial Device Server Serial to ethernet converters --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/606900805-tzone-rs485-temperature-sensor-modbus-rtu-temp-humidity-transmitter-analog](https://www.desertcart.in/products/606900805-tzone-rs485-temperature-sensor-modbus-rtu-temp-humidity-transmitter-analog) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-07-06*
