## Questions & Answers

**Q: Does product include modbus register map?**
A: Yes..., it includes pre-defined memory map locations where you can read the Temperature and Humidity value,
and also includes memory locations where you can write an Off-Set value to the Temperature and Humidity
sensor to calibrate them.

**Q: Where do I download the manual ?**
A: Seaech on interbet model and you find manual and instructions.

**Q: Does it requires programming? does it comes with a manual if so?  is the data transmitted without rs485 request? at what periodic rate if so?**
A: It may or may not require programming..., provided if you want to calibrate the sensors.
But you will definitely have to communicate with the sensor.
 
And either Modbus RTU or UART RS-485 are the only two methods.
You will have to web search how these protocol work. The Baud Rate is 9600.

Yes it comes with a manual and you can also download it from the web.

Modbus RTU is a software communication protocol which incorporates RS-485, the serial hardware communication protocol.
So you can find a lot Modbus RTU protocol out there on the web..., some free and some paid for.
I bought the paid-for ones because i wanted all the flexibility in the software.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excelente por una fracción del precio.
*by A***Z on July 1, 2024*

Lo utilice para conectar con una pantalla HMI , trabajo muy bien y a un excelente precio , probablemente alguien no supo como funciona.

### ⭐⭐⭐⭐ Its ok
*by R***P on June 17, 2020*

I bought this sensor for a home automation project based on an Allen Bradley Micro820 PLC. The sensor seams to work really well once you get it configured. The available documentation is a nightmare and i dont know if the fault mainly lies with this sensor or with Connected Components Workbench but after many hours of crazy frustration i found the address and speed settings at 0x3 286 not at 0x3 101 as stated in the docs. Then it turned out that the temps and humidity were interpreted strait to c and %, no hex conversion required, which was a bonus at that point. I get nice high resolution trending on the humidity but the temp is not nearly as good.Once i set the new address and comm speed i had to power cycle the unit for it to take effect

### ⭐ Not accurate and don't calibrate
*by D***E on June 28, 2022*

I bought 3 of these and they are all way off for both temp and humidity. The best one is 10%RH off, and a few degrees. I adjusted the calibration registers, can read back that they were properly written to, but the values it outputs do not change at all. Power cycled them, etc, no change. I will play around with them a little more, but will likely be returning them for a refund.As another customer said, they are well made, its just a shame they aren't accurate and don't calibrate.Upon further inspection, this product doesn't even use the sensor listed on the product page (SHT20), it has a SHTC3 sensor...
