Highlights:

1. MAX31865 is a simple and easy-to-use thermistor-to-digital output converter optimized for platinum resistance temperature sensor (RTD).

2. Sensitivity of RTD used in setting external resistance, high precision ∑ -ADC converts the ratio of RTD resistance to reference resistance into digital output.

3. The input of MAX31865 has over-voltage protection up to 50V of soil, providing configurable RTD and short circuit condition detection of cable.

Parameters:

Name: MAX31865 Platinum Resistance Temperature Measurement Module

Instruction mode: AT instruction

Power supply: 5V

PCB size: 51mm * 33mm (long X width)

Installation hole spacing: 44mm X25mm (long X wide)

Measuring mode: 2, 3 and 4 lines (our store is configured to use PT100 resistor with 3 lines by default)

Temperature measurement range: - 200°C ~650 °C(- module temperature measurement range is mainly determined by platinum resistance, the highest temperature of PT100 platinum resistance matched by our shop is about 250°C

Alarm threshold: alarm can be set for low or high temperature (also can be set to alarm within a certain temperature range)

Default platinum resistance type: PT100 (PT1000 requires the user to purchase and change the reference resistance value)

Package include:
