Precautions

• When this device is used in combination with an LED lamp, the lamp must be an infrared LED lamp.

• To stabilize the power line, insert a bypass capacitor of up to 0.01 μF between VCC and GND, close to the device.

• When the power is turned on, the output value will fluctuate for 1 ms as the internal circuit stabilizes.
