Light Sensor Switch Photosensitive Resistance Relay Module Description Brand new and professional module
High quality photosensitive resistancerelay module
1 Adoptsphotosensitive resistance to sense the strength of light,together usewithrelay, can directly control the load
2 Euipped with potentiometer to adjust the sensitivity. Set and startthe relay threshold value by adjusting the potentiometer. When the strengthof light islower thanthis threshold value,relay modulewill attract to close while it ishigher than the threshold, the relay module will break off
3 12V power isspecially used forthe relay.Onboard 78L05 regulator transistors is used forsensor and comparator,to make the product more stable and reliable;
4 Onboard opto-isolator driven relay, can effectively protect the chip, to make surethe product more reliable work.
5 With four mounting bolts holes for easy installation
6 Size:5x2.5x 1.8 cm, cable length 50 cm
7Weight:20 g
8Adoptswide voltage LM393 comparator
9 Working voltage: DC 12V
10 Working current: > 100mA
11 Output forms: AC 250V 10A or DC30V 10A ( can beused within the range of lower than 10A current )Function:
Light detection, brightness detection, test and adjust brightness threshold via potentiometer, comes with relays, can do all kinds of brightness detection switch.
Can control various street lights.They can automatically be opened at night while automaticlly shuts off in the daylight and control the car gadget and automatic equipment.Instruction:
1 Photosensitive resistance sensor module is very sensitive to light of environmental. It isgenerally used to detect the brightness of ambient light.
2 Whenthe brightness of ambient lightis lower thanthe set threshold value, the relay attracts to close and the common port and normal open port will be connected; while the brightness of the ambient lightexceeds thanthe set threshold value, the relaybreaks off and the common port and normal close port will be connected.
3 The common port, normal open and normal close port are equivalent to a double control switch. When there is electricity in the relay coil, the common port and normal open portare connectedwhile there is no electricity in the relay coil, the common port and normal close port are connected.
Package Included 1 x Module
