MB bus Temp Sensor - digital temperature sensor -55 ° C + 125 ° C on RS485

The MB Temp Sensor device is an electronic device that allows you to control the temperature from -55 ° C to + 125 ° C of an object or environment via a PC or Embedded system. For the measurement it uses a digital sensor that guarantees high measurement accuracy and an accuracy of ± 0.5 ° C from -10 ° C to + 85 ° C.

The device is composed of a logic and a temperature sensor: it is possible to keep both units together or to keep them separate and connected by means of a 3-wire cable (not supplied) which allows you to place only the sensor on the object or in the environment and logic elsewhere. In this case it is advisable not to exceed 10 meters in length of the cable that connects logic and sensor to avoid possible errors from interference in the readings.

The sensor requires 750ms to carry out a temperature conversion, therefore in order not to interrupt other commands to the devices of the MB bus, during this time, the commands for the start of conversion and the final temperature reading have been divided. It is also possible to carry out a conversion on several sensors with a single broadcast command with the correctness control of the conversion.

The device is designed to be installed in an RS485 network allowing the installation of the device together with other 30 devices of the same MB family, being able to create a powerful home or industrial automation system.
