Description

This product is retired, please consider the new version Grove - Light Sensor V1.2.


The Grove - Light sensor module uses GL5528 photoresistor(light dependent resistor) to detect the intensity of light in the environment. The resistance of photoresistor decreases when the intensity of light increases. A dual OpAmp chip LM358 on board produces voltage corresponding to intensity of light(i.e based on resistance value). The output signal from this module will be HIGH in bright light and LOW in the dark.


This module can be used to build a light controlled switch i.e switch off lights during day time and switch on lights during night time.


For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.

Hi,I have been reading the example code for this sensor and I have two questions about this formule: Rsensor=(float)(1023-sensorValue)*10/sensorValue;1) If I am using a 12 bits ADC and 3,3 VCC source power, how is the new version of this for

Thanks for your answer Luo G,Yes, I'm using a microcontroller with a 12 bits ADC and with 3,3 V as VCC. Also, about the second question, I need to get luxes or lumens units and I don't know how I can use Rsensor value to get luxes or lumens untis f

could anyone elaborate a bit more on this formula? what is the logic behind this formula? what the values mean and what do we compute? Rsensor is the analog value of the resistance of the sensor or the digital (because is cast to float is the analog value?) ? Thanks in advance!

You can get a resistance value which is associated with light intensity.Then you need to refer to the resistance curve of LDR GL5528 to know the LUX.

My bad. 6 months ago, I asked you a question in a rather round about way. Today, you answered it with a meaningless answer. So the proper question, which I hope you might answer in less than 6 months:Can your LiPo rider product be damaged by vo

Hi Philippe.Those resistors are reserved for some special devices,such as iphone.And the current of output is depended on your load.If your load is too small,the current would be more larger,so maybe you can add a external circuit to your devices,but n

Hey,You can use this rule:GND to GND, VCC to 5V,NC need not to connect(just ignore it),and SIG to the pin which you want to connect.____have a try~enjoy

Hi Chris, you could refer to its schematic, find DONE pin of CN3065, solder a wire to connect it to your Arduino pin to monitor charging status. Another method, find LIPO_BAT pin, monitor the voltage by Arduino analog port.
