It supports Modbus RTU protocol over RS485 with up to 1200m transmission range and configurable baud rates (4800/9600/19200 bps). Its IP65 waterproof rating and DIP switch address setting make it ideal for multi-sensor industrial applications including HVAC, warehouses, and greenhouses, combining compact design with low power consumption for seamless integration. ## Description Product Description Industiral Temperature and Humidity Sensor High accuracy SHT3X sensor Measuring and monitoring temperature humidity data Long transmission distance Low power consumption RS485 Temperature and Humidity Transmitter Modbus RTU RS485 Output Electrical Interface VCC: Positive pole of power cord (Red Line) GND: Negative pole of power supply (common terminal with ground wire) (Black Line) T: Temperature current output (White Line) RH: Humidity current output (Yellow Line) DIP Switch DIP switch supports setting address to facilitate sensor identification. Supports simultaneous monitoring of multiple temp humidity sensors through monitoring devices. The standard MAX transmission distance is about 1200 meters, depending on the use environment, transmission material and transmission rate. Package Content Temperature and Humidity Transmitter *1 User Manual *1 The parts required for installing equipment Review: good accuracy - I have been using this in my garage poking out of a little hole to get an idea of the outside temperature that I can then use in automations downstream. This seems to be accurate, and I have no communication errors - I haven't played around with anything other than leaving it at the defaults. They seem to work well enough, so I'm leaving it how it is. I haven't been able to use it with multiple being monitored, but there's nothing I can see that would suggest it wouldn't work. It's well documented, which makes it easy to set up and use without too much fuss. The reason for deducting a star is I share the other reviewers concern about the water-proofness over time - feels like there should be an extra o-ring to keep water out of the top and this feels like an oversight. I have it under a sofit so for me it shouldn't be too much of an issue. but if there was regular water exposure i would be a little worried. Review: Works Perfectly - Device seems to work perfectly, I ran it at 50ms comms interval for a couple of hours with no transmission errors at all using the default 9600,8,N,1 Settings. (you can configure the baud rate 4800, 9600 and 19200 only) Temperature and Humidity both have 0.1C/% Resolution, no issues with the accuracy for my use case as far as I can tell. Holding Registers 0 and 1 return temp and humidity, the rest is settings or identification. Where I do have a slight concern is how waterproof or industrial this is, the actual sensor PCB is waterproofed at the top where it goes into the black plastic ring, but then that ring itself then doesnt have any kind of o-ring to the grey body (though the 2 grey parts do have an o ring between them where you unscrew them to set the Slave Address) so I suspect water may get in over time at the top. Hopefully I am wrong. Its also all plastic construction, not cheap, but it also doesnt feel particularly industrial, which given the price I think I maybe was expecting a slightly stronger build quality. However I cant deny that it works well. ## Features - RS485 Temperature and Humidity Sensor -- The industrial temp sensor uses the newly designed CMOS chip SHT3X sensor, high accuracy and makes its performance more stable in high humidity environments; IP65 waterproof - Modbus Temperature Sensor with DIP Switch -- Supports simultaneous monitoring of multiple temp and humidity sensors through computers or other monitoring devices; DIP switch design to set the address to facilitate sensor identification - Parameters -- Temperature measuring range is -40℉ to 257℉ (-40℃ to 125℃) and humidity measurement range is 5% to 95% RH; DC:5 to 24V; Transmission rate(optional):4800 bps / 9600 bps / 19200 bps - RS485 Temp 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 - Easy to Use -- Low power consumption and strong resistance to chemical pollution; Small and compact, light weight, easy to carry and install, does not take up much space - Wide Application -- This analog temperature humidity transmitter is ideal for industrial, HVAC, communication room, warehouse buildings, automatic control applications, PLC, greenhouse, celler and so on to monitor temp and humidity data ## Images ![TZONE RS485 Temperature Sensor Modbus RTU Temp Humidity Transmitter Analog | Industrial Temp Sensor RH Monitor for HVAC PLC Greenhouse Office Waterproof - Image 1](https://m.media-amazon.com/images/I/51ZQPaEwuuL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐ good accuracy *by C***W on 23 March 2026* I have been using this in my garage poking out of a little hole to get an idea of the outside temperature that I can then use in automations downstream.
