Generic وحدة استشعار حراري رقمية 2D10B Ky-028

Digital and Analog Outputs, Adjustable detection threshold

Connect the board’s analog output (A0) to pin A0 on the Arduino and the digital output (D0) to pin 3. Connect the power line (+) and ground (G) to 5V and GND respectively. When the temperature threshold is reached, the digital interface will send a HIGH signal turning on the LED on the Arduino (pin 13). Turn the potentiometer clockwise to increase the detection threshold and counter-clockwise to decrease it. Since the analog output pin is directly connected to the potentiometer it isn’t possible to use the Steinhart-Hart equation to calculate the temperature as we did with the KY-013, we can only use this value to measure relative changes in temperature.
