Works as described
Accurate temperature readings and simple integration with Home Assistant. The documentation provided by the seller was helpful for configuring the Modbus address.

Reliable data acquisition
I've deployed ten of these in a greenhouse project. They handle the moisture perfectly, and the data logging via Modbus has been uninterrupted for three months.

Good value, easy setup
Setup was straightforward using a USB-to-RS485 converter. The readings are consistent with our calibrated thermometer. Only minus one star because the cable could be a bit more flexible.

Excellent precision
Compared this against a high-end laboratory thermometer, and the deviation was negligible. For the price, you cannot beat the precision and build quality.

Robust construction
The stainless steel probe feels very durable. I submerged it in a water tank to test the IP68 rating, and it performed without any issues. Great product.

Perfect for industrial monitoring
This sensor works flawlessly with our PLC system. The Modbus communication is stable, and the waterproof probe holds up well in humid environments. Highly recommended for factory use.
Q: Does this support multiple sensors on the same bus?
A: Absolutely. RS485 is a multi-drop bus, so you can connect up to 32 devices (or more with repeaters) on the same two-wire line, addressing each sensor individually.
Q: Can this sensor be connected directly to an Arduino?
A: No, this module outputs an RS485 signal. You will need an RS485 to TTL converter (like a MAX485 module) to interface it with an Arduino or similar microcontroller.
Q: Can I use this in saltwater aquariums?
A: While the probe is IP68 waterproof and made of stainless steel, prolonged exposure to highly corrosive saltwater may eventually affect the housing. We recommend regular inspection if used in marine environments.
Q: Is the cable length extendable beyond 2 meters?
A: Yes, the RS485 protocol supports long-distance transmission. You can extend the cable up to 1200 meters using shielded twisted pair cable, provided you maintain proper termination resistors.
Q: What is the default Modbus address and baud rate?
A: The default slave address is 01, and the default baud rate is 9600 bps with 8 data bits, no parity, and 1 stop bit. These can be modified via software commands.
