EZO™ RTD Temperature Circuit
| Article number: | Part # EZO-RTD |
| Availability: | In stock (19) |
Connect your Temperature sensor to this circuit to create a workable signal for your microprocessor using UART or I2C protocol.
Works with any brand and type of PT-100 / PT-1000 sensor.
The most important part of calibration is watching the readings during the calibration process. It's easiest to calibrate the device in its default state (UART mode, continuous readings). Switching the device to I2 C mode after calibration will not affect the stored calibration. If the device must be calibrated in I2 C mode be sure to request readings continuously so you can see the output from the probe.
Calibration can be done at any value, a simple method is to calibrate the probe in boiling water.
