Industry standard chip
Using the MAX31865 chip ensures reliability. Great for industrial temp monitoring where precision matters.

Good module, tricky wiring
The module itself is great but setting up the 3-wire configuration took some reading. Once done, very stable.

Fast delivery
Arrived quickly and well packaged. Tested immediately with PT100 sensor and it worked out of the box.

Perfect for my kiln project
Works flawlessly with my Raspberry Pi. Accuracy is spot on compared to my thermocouple. Very stable readings over long periods.

Works but needs library
Had to search for a compatible Arduino library. Hardware is fine though, just wish documentation was clearer.
Q: Can it measure below zero?
A: Yes, it supports temperature ranges well below freezing depending on the specific sensor used.
Q: Is the logic level 5V tolerant?
A: The module operates at 3.3V. Please use a logic level converter for 5V microcontrollers to avoid damage.
Q: Does this support PT1000 sensors?
A: Yes, this module supports both PT100 and PT1000 sensors via jumper selection on the board.
Q: Is the sensor included in the package?
A: No, this is only the breakout board. Sensors are sold separately to allow for custom probe lengths.
Q: What is the sampling rate?
A: The conversion time is typically around 60ms per sample, allowing for roughly 16 readings per second.
