ماژول سنسور دمای دیجیتال مدل KY-028

ماژول سنسور دمای دیجیتال مدل KY-028

سنسور دما KY-028 تغییرات دما را بر اساس مقاومت ترمیستور اندازه گیری می کند. این ماژول دارای هر دو خروجی دیجیتال و آنالوگ است ، یک پتانسیومتر برای تنظیم آستانه تشخیص خروجی دیجیتال وجود دارد.

Introduction 

The thermal resistance of the module is very sensitive to the ambient temperature , typically for detecting the temperature of the surrounding environment.

Through the potentiometer adjustment, you can change the temperature detection threshold ( ie, control temperature ) , such as the need to control the ambient temperature is 50 degrees , the module in the corresponding ambient temperature to its green light ,

Temperature measurement range: -55°C / +125°C This module includes a NTC Thermistor – its resistance falls with higher temperature.Digital Out: While measuring a temperature which is higher than the limit value, it will be shown here – you can set the limit value via potentiometerAnalog Out: Direct measurement of the sensor unitLED1: Shows that the sensor is receiving powerLED2: Shows that a magnetic field was detected
