Photoresistor/LDR Light Sensor Module due 20 dBm radio amplifier testedPhotoresistors, also known as light dependent resistors (LDR), are light sensitive devices most often used to indicate the presence or absence of light or to measure the light intensity. In the dark, their resistance is very high, sometimes up to 1M, but when the LDR sensor is exposed to light, the resistance drops dramatically, even down to a few ohms, depending on the light intensity. LDRs have a sensitivity that varies with the wavelength of the
