XY-TR01 Digital Temperature & Humidity Control Module The XY-TR01 Digital Temperature and Humidity Thermostat Module is great for controlling humidity and temperature. It has a digital sensor called SHT20. In addition, its user interface comes with a digital display to show data and four control buttons to adjust humidity and temperature. The module also has two separate relays (maximum current: 10A) to independently control the cooling/heating and humidification/dehumidification m...

What is Temperature Switch/Thermo Switch/Thermostat? Thermo Switches are smart little devices that operate automatically when they reach a specific temperature (either open or close). They’re a crucial part of heating/cooling systems because they control and regulate the temperature. How do Thermal Switches Work? Thermo switches operate based on the contraction and expansion of a bimetallic strip and the difference in their expansion coefficient. In this article, we won’t go into much detail, but to p...

Introduction The KY-028 module contains a thermistor sensor that measures the ambient temperature. The resistance of the thermistor varies inversely with temperature. In addition, the analog and digital output pins provide the sensor's data. When the value measured by the sensor exceeds the threshold, the digital pin goes HIGH, lighting up the LED on the module. Tip You can adjust the digital output threshold using the blue potentiometer on the module. KY-028 Pi...
