MAX31865 High Precision Isolated Temperature Collector Module PT100 Serial Port:
$13.85
Features:
1.MAX31865 high-precision temperature controller
2.Serial port output
3.Upper computer debugging
4.3 alarm modes
5.AT instruction
Attention:
1.The default support for the temperature controller is PT100 platinum resistor. If you need to use a PT1000 platinum resistor together, you need to adjust the temperature
The reference resistance of the device has been changed from 402 ohms (4020) to 4.02K ohms (4021), with an accuracy of 0.1% and a packaging of 0805
2.The thermostat is compatible with 2-wire/3-wire/4-wire platinum resistors by default. The connection method between them and the thermostat is different, and it needs to be switched by changing the jump cap on the thermostat.
Parameters:
Temperature testing range: -200 ℃~650 ℃ (depending on the matching platinum resistance temperature measurement performance)
Working temperature range: -20 ℃~80 ℃
Resolution: 0.1
Accuracy: The total accuracy remains at 0.5% (0.05% of full scale) (depending on the temperature measurement accuracy of the matched platinum resistor)
Setting method: button/serial port AT command
Instruction mode: AT instruction
Display mode: 0.36-inch Nixie tube displays 5-digit red
Working voltage: DC 3.3-5V
Working current:<100mA
Power interface: MicroUSB/power port
Data communication interface: TTL pin arrangement
Platinum resistor interface type: compatible with 2-wire/3-wire/4-wire, fixed with KF850 terminals
Default platinum resistance type: PT100. If using PT1000, the reference resistance value of the internal patch of the module needs to be changed
Package include:
