Description
- LDR comes from the abbreviation of 'Light Dependent Resistor' and it means light dependent resistor. LDR is also called photoresistor. LDR, which is a passive sensor as well as being a resistor type, changes in its structure depending on the light intensity. LDR Light Sensor Board allows us to connect our ldr sensor directly to devices such as arduino without the need to set up an external circuit. The LDR light sensor board also outputs both analog and digital. You can measure by connecting the analog output pin directly to one of the analog pins of the Arduino. There is also a digital output pin on the board. It gives HIGH output when the detected light amount exceeds the threshold value, and LOW output when it falls below the threshold value. The threshold value required for the digital output is made with the trimpot on the card. Technical Specifications: Operating Voltage: 3.3-5 V
- Output Type: Analog and Digital
