Application of smart LED lights and NTC thermistor.Human motion sensing module wholesaler

　　LED lights can be seen everywhere in our lives. Like any other semiconductor device, high brightness and high -power LED will generate heat. As we all know, high temperature can significantly shorten the life of LED and affect its brightness, so temperature control is required. So smart LED lights came into being. In order to control the temperature, it is necessary to determine how to monitor the temperature of the LED tube core. This is exactly the role of negative temperature coefficient (NTC) thermistor in the LED lighting system.

　　The sensitivity of NTC thermal resistance to temperature changes, even if it increases slightly, can use the device for temperature sensing/control applications. These devices allow LEDs to withstand higher currents (compensation) throughout the temperature to improve the service life of LEDs. The current can be controlled according to the ambient temperature through the NTC thermistor.

　　In addition, the NTC thermistor in the smart LED light can not only monitor the ambient temperature and humidity, but the obtained data will be transmitted to the microcontroller to judge, thereby realizing the intelligent function.

　　The main characteristics of the product:

　　1. Multi -layer structure allows different resistance values in the same B constant

　　2. Super small size, low capacitor, high B value

　　3. Glass coating has long -term reliability

　　5. Non -polarized for installation

　　6. The possibility of flowing/backwing welding

　　There are 4 SMD sizes (1206/0805/0603/0402)

　　Chip size (long x wide):

　　02 (0402) -1.0 × 0.5mm

　　03 (0603) -1.6 x 0.8mm

　　05 (0805) -2.0 x 1.25mm

　　06 (1206) -3.2 x 1.6mm

　　The resistance at 25 ° C:

　　102 = 10 × 102 = 1,000Ω

　　103 = 10 × 103 = 10,000Ω

　　104 = 10 × 104 = 100,000Ω
