Modbus temperature sensor is the most used or the most common Modbus in the modern industry. Modbus temperature sensor enables communication among many connected sensors and other devices to the same network. The result from the Modbus temp. sensor (Modbus temperature sensor or any other) is communicated directly to a computer. Modbus protocol is used also to connect a computer with a remote terminal unit called „RTU“ in SCADA systems (Supervisory Control And Data Acquisition).
1. What is Modbus?
Modbus is an industrial protocol standard that was created by Modicon in the late 1970s for communication among programmable logic controllers (PLCs). Modbus remains the most widely available protocol for connecting industrial devices. The Modbus protocol specification is openly published and the use of the protocol is royalty-free.
In simple terms, it is a method used for transmitting information over serial lines between electronic devices. The device requesting the information is called the Modbus Master and the devices supplying information are Modbus Slaves. In a standard Modbus network, there is one Master and up to 247 Slaves, each with a unique Slave Address from 1 to 247. The Master can also write information to the Slaves.
The most commonly used form of Modbus protocol is RTU over RS-485. Modbus RTU is a relatively simple serial protocol that can be transmitted via traditional UART technology. Data is transmitted in 8-bit bytes, one bite at a time, at baud rates ranging from 1200 bits per second (baud) to 115200 bits per second. The majority of Modbus RTU devices only support speeds up to 38400 bits per second.

2. Indoor and Outdoor Modbus Temperature Sensor?
The most popular product is outdoor sensor ANDAUTF/MD because it can be mounted to any surface outdoor. The sensor itself is totally protected inside of the IP65 housing. But on the other hand, if you need to measure the temperature inside the room, we can also provide you a beautiful indoor Modbus temperature sensor.
Modbus Outdoor Tempetature Sensor ANDAUTF/MD RS485 sensor is available with all conventional sensor types. Temperatures are recorded inside the sturdy and humidity-resistant plastic housing. The housing has an IP54 protection class. The ANDAUTF/MD is mainly used in weather-dependent environments, such as outer walls, where direct insolation should be avoided.
Modbus Indoor Tempetature Sensor Surface-Mounted ANDRTF3/MD RS485 sensor is for measuring the temperature in living and office spaces, reception halls, foyers, etc. The modern and plain design allows for easy and inconspicuous mounting. The housing has an IP20 protection class.

4. Is Sensor with Modbus the Best Sensor?
Is the sensor who communicate with Modbus the best and the most precise sensor in our product range? The short answer is no. There’s no advantage or disadvantage if sensors are mounted and configured correctly. We manufacture passive temperature sensors, active temperature sensors, and even sensors which works on Modbus protocol. All of them are made by the strict industrial standards.
At the end of the day, the most important thing is that sensors are reliable and that the measurements are correct and precise. At Andivi we strive to manufacture the best possible sensors.
All our sensors, including Modbus, are 100% made in the EU and have 3 years of warranty! The quality speaks by itself.
