รายละเอียดสินค้า (Description)

Operating temperature range: -20Celsius to 80Celsius
Resolution: 0.1
Accuracy: The total accuracy is maintained at 0.5 (0.05% of full scale) (depending on the temperature measurement accuracy of the matched platinum resistance)
Setting method: button/serial AT command

Command mode: AT command
Display mode: 0.36 inch digital tube display 5 digits red
Working voltage: DC 3.3-5v
Working current: Less than 100mA
Power supply interface: Micro-USB/power hole
Data communication interface: TTL header
Platinum resistance interface type: compatible with 2-wire/3-wire/4-wire, fixed with KF850 terminal
Default platinum resistance type: PT100, if you use PT1100, you need to change the internal patch reference resistance of the module
1. The thermostat supports PT100 platinum resistance by default. If you need to use PT1000 platinum resistance, you need to change the reference resistance of the thermostat from 402 ohms (4020) to 402K ohms (4021), the accuracy is 0.1%, and the package is 0805, refer to the appendix wiring manual for details.
2. The thermostat is compatible with 2-wire/3-wire/4-wire platinum resistance by default. The connection methods between them and the thermostat are different. You need to change the jumper on the thermostat to switch. For the specific wiring method, refer to the appendix wiring Manual
