## Overview

This 5mm Photodiode Sensor Module offers directional light brightness detection with adjustable sensitivity, delivering both digital and analog outputs. Designed for easy integration with 3.3V-5V microcontrollers like Arduino, it features a compact PCB with mounting holes, making it ideal for precise ambient light sensing in professional and DIY applications.

## Description

Instructions for the use of the photodiode sensor module: 1 The photodiode module is most sensitive to ambient light intensity and is generally used to detect the brightness of the surrounding environment and light intensity, which can be used with the photoresistor sensor module on most occasions. The difference between the two is therefore, that the photodiode module has good directivity and can sense the light source in a fixed direction. 2 When the module has no light conditions or the light intensity does not reach the set threshold, the DO port outputs a high level, When the ambient light intensity exceeds the set threshold, the module D0 outputs a low level; 3 The digital output D0 of the small board can be directly connected to the microcontroller, and the highLow level to detect changes in ambient light intensity; 4 The digital output DO of the small board can directly drive the relay module of our store, which can be composed of a photoelectric switch; 5. The analog output AO of the small board can be connected to the AD module of our store, and through AD conversion, more accurate values of the ambient light intensity can be obtained

Review: On/Off response times are perfect for my project - My project, a nightlight application, requires that the photodiode module accurately measure the ambient light when the illuminating light (an LED array) is turned OFF under program control. As the photo of the 'scope trace shows, the ON and OFF response times of the photodiode module are about 3 ms, which implies that I can turn the LEDs OFF, every 30 minutes or so, check the ambient light level, and then, if the ambient light level is still below the set threshold, turn the LEDs back ON without a noticeable "blink" to the human eye. If the ambient light level is above a set threshold, then the LEDs will remain OFF.
Review: Quiet mind - Pull up collector resistor req. for Do. Add capacitor on Vcc as per noise on cable type. Module function OK.

### ⭐⭐⭐⭐⭐ Lots of uses for this light sensor
*by Y***O on January 15, 2024*

I've been testing (playing with) the photodiode sensor module and it's rather simple to use. There are 4 pins, 2 for ground and power. Then there is a digital pin that just indicates if light is present or not (high and low). And lastly there is an analog pin that provides the level of ambient light seen by the sensor. I've just been using the digital pin in a quick project where I connected a module to a relay in order to turn on a radio when the lights go out. The next project will be to add a module to my Arduino robot car to follow a light. There are 10 modules in the package so I can use them in many projects. This is a good way to learn more about light and how it can interact with electronics. The price point for the package is quite reasonable. I'm enjoying this set of modules.
