Comparator chip LM393 ,it is stable.
Can detect the ambient brightness and light intensity
Accuracy adjustable
Operating voltage 3.3V-5V
Output: DO digital switch outputs (0 and 1) AO analog voltage output
power indicator and digital switch output indicator
With a mounting screw hole
PCB size: 3.1cm * 1.5cm
Interface Description (4-wire):
1 VCC -- 3.3V-5V voltage
2 GND -- GND
3 DO -- board digital output interface (0 and 1)
4 AO -- board analog output interface
Introduction:
This module is sensitive to the light, Usually used for detecting the ambient brightness and light intensity.
When there is no light or the light intensity can not reach the value,DO output is high level.when light intensity over than the value, the module DO output is low level.
The module digital output DO can be directly connected with the microcontroller,use microcontroller detect high or low level, so that can detect the environmental light intensity change.
Can use this board digital output DO port drive relay module directly(our store on sale these relay modules), can use as a photoelectric switch.
The analog output AO connect with AD module,it can get more precise light intensity value through the AD converter.
Package Included:
2 x module

Before you make your purchase, it’s helpful to know the measurements of the area you plan to place the furniture. You should also measure any doorways and hallways through which the furniture will pass to get to its final destination.Picking up at the store
Shopify Shop requires that all products are properly inspected BEFORE you take it home to insure there are no surprises. Our team is happy to open all packages and will assist in the inspection process. We will then reseal packages for safe transport. We encourage all customers to bring furniture pads or blankets to protect the items during transport as well as rope or tie downs. Shopify Shop will not be responsible for damage that occurs after leaving the store or during transit. It is the purchaser’s responsibility to make sure the correct items are picked up and in good condition.Delivery
