Descriptions: This is a DIY Infrared Reversing Indicator kit parts. You should solder it by yourself.According to the infrared reaction, measure the distance and change the output transition.It can be applied to intelligent robots, smart homes, industrial controls and so on. 2. Features: 1>.High sensitivity; 2>.Short sensing distance; 3>.Low power consumption; 4>.Inductive distance adjustable; 5>.Working status indicator; 6>.Wide operating voltage range; 7>.Low power consumption; 8>.DIY design. 3.Parameters : No. Parameter Value 1 Model IRS-30 2 Standby current Less than 15mA 3 Soldering difficulty Level Easy 4 Working voltage DC 5V-9V(Recommend 5V) 5 Working current Less than 90mA 6 PCB Size 67*41mm 4.Working principle: 1>.When light hits the surface of the object, it radiates and emits part of the light. Through this principle, the receiver is used to receive this portion of the light to output a signal. According to a series of circuits, the distance range is indicated by an indicator. 2>.This circuit uses the modulated invisible infrared to detect the distance and has the advantage of anti-interference! 3>.When the object is in front of the light source about 30cm,LED3 will ON;When the object is in front of the light source about 20cm,LED2 will ON;When the object is in front of the light source about 10cm,LED1 will ON; 4>.The working voltage of this kit is DC5-9V, the recommended voltage is 5V. 5.Potentiometer description There are two potentiometer on PCB.They have different function as shown: VR1 : It is used to adjust distance. VR2 : It is used to adjust sensitivity regulation. 6.Instructions: Step 1: Complete the installation in the normal way following installatio ProductSiteLaunchDate : 2021-04-09T15:08:54.966Z UnspscCode : 39120000 Voltage1 : 5 volts Voltage2 : 9 volts
