Flying Fish Light Sensor

There are various similar models on e bay aliexpress and other places all vary slightly.

Flying fish light sensor.

Here a conventional ldr photoresistor is applied to a breakout board and equipped with comfort functions. The digital output has a trim potentiometer that can be used to set a trigger light level. Two types of code is provided so you can either use digital outp. Illuminates when power is applied.

It s a light detection sensor which i connected to the arduino nano to test its functionality. They are all based on the comparator ic lm393. Pin control indicator description. Output that goes low when obstacle is in range.

The lm393 is a simple photo resistor light sensor that has both analog and digital outputs. I try to use the rain sensor to detect some dripping water in a drainage system of my house. Please try again later. You can buy this mh series of cheap sensors often called flying fish in the arduino world.

Digital output d0 directly connected to the mcu and detect high or low ttl thereby detecting ambient light intensity changes. In the following example we will use the analog output to measure light level. There are a number of different sensors for measuring light available on the market. If you are interested in reading the digital output please refer to the pulse.

They come in a range of configuration ldr ntc thermistor resistive water moisture detectors and more. In this video you will learn how to turn ac bulb on at night and turn it off during the day. I add that the angle subtued by the fish at any distance will be so small that the reflected light from it will be minute compared to the background clutter and the ambient light. It is mainly about the brightness of ambient light sometimes also about invisible infrared light from cheap to expensive.

Hope this is useful to somebody. It servs the amount of light from 0 very bright to 1024 very dark using the analog pin. 3 3 to 5 vdc supply input. It ain t gonna work unless you dangle the fish a few inches in front of the ir stuff with your hand.

Module light conditions or light intensity reach the set threshold do port output high when the external ambient light intensity exceeds a set threshold the module d0 output low.
