Infrared light board production process

Infrared light board, it is the night light of infrared camera, most of the light board is integrated in the camera shell. There is a light control switch on the infrared light board, which is what we often call the photoresistor, because of it, the camera can control the opening and closing of the infrared light. 1. The raw materials are prepared, and the engineer designs the PCB plan, and then hands it to the PCB manufacturer for the printed circuit board. Then there is the purchase of raw m

The difference and working principle of photodiode and infrared pair tube

The infrared sensor is manipulated according to the conversion of light intensity into an electronic signal. Infrared sensor is generally composed of three parts: transmitter, signal receiver and test power circuit. The signal transmitter aligns the transmitted light, and the transmitted light generally comes from semiconductor material lamp source, light-emitting diode (LED), laser diode, infrared emitting tube. The light is sent without interruption or the pulse width is changed. The signa
