특징

  • EZO Carrier Click - RTD is a compact add-on board engineered to provide temperature readings across a broad range of temperatures. This board features the EZO-RTD™, an embedded temperature circuit board from Atlas Scientific. The EZO-RTD™ is a small black additional board that comes together with the carrier board and allows you to read the temperature values from -126.000°C to +1,254°C with a resolution of 0.001°C. The EZO-RTD™ allows readings in a maximum of one reading per second. This Click board™ is ideal for high accuracy for precise temperature readings from any class of 2, 3, or 4-wire platinum RTD probes, such as the PT-1000 Temperature Probe from Atlas Scientific.

  • HOW DOES IT WORK?

    EZO Carrier Click - RTD is based on the EZO-RTD™, an embedded temperature circuit board from Atlas Scientific. It is specifically designed to be used in applications where accurate and precise temperature measurements are required through a generic PT-100/PT-1000 temperature probe or any class of 2, 3, or 4-wire platinum RTD probes. It works from -126.000°C to +1,254°C with a resolution of 0.001°C. Additionally, the temperature output options include Celsius (°C), Kelvin (°K), or Fahrenheit (°F), catering to diverse user preferences.

    As known, the most important part of probe calibration is watching the readings during the calibration process. It's easiest to calibrate the device in its default state (UART mode, continuous readings) at any value - a simple method is to calibrate the probe in boiling water (100°C). Like any other part of the EZO™ family, the EZO-RTD™ also features Sleep mode, Continuous operation, Find function, Export/Import calibration, On-module status LED, and many more features detailed and described in the attached datasheet.

    EZO Carrier Click - RTD can use a standard 2-wire UART interface to communicate with the host MCU with the default baud rate of 9600bps. While using the UART interface, you can use the library we provide or a simple ASCII set of commands. You can also choose a standard 2-wire I2C interface over the COMM SEL jumpers. The EZO-RTD™ needs to be isolated from the host MCU; therefore, this Click™ board comes with the Si8400AB, a bidirectional isolator from Skyworks. The isolator provides standard bidirectional and I2C communication with a clock frequency of up to 1.7MHz. So, to eliminate the electrical noise, besides the Si8400AB isolator, the power supply voltage is also isolated. For this purpose, this Click™ board is equipped with the ROE-0505S, a DC/DC converter from Recom.

    This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
