The keyestudio TEMT6000 Ambient Light Sensor provides an accurate way to measure ambient brightness with improved precision compared to traditional phototransistors. Designed for compatibility with Arduino projects, this sensor is perfect for applications where light sensitivity is vital.
The TEMT6000 mimics human eye sensitivity and effectively reacts to changes in light levels, making it a versatile tool for various electronic projects.
It works exceptionally well in reacting to very small changes across a wide range of brightness. However, since it is meant to mimic the human eye, it does not respond well to IR or UV light, so be sure to consider this when utilizing it in your project.
Key Features
- High Sensitivity: Tailored to detect ambient light levels, making it an ideal choice for light-dependent applications.
- Wide Operating Voltage: Functions under a supply voltage of +5V DC, ensuring compatibility with most microcontrollers.
- Compact Size: Its small dimensions (36.5mm x 16mm) and lightweight design (4g) make it easy to integrate into various devices.
- Simple Setup: Requires minimal connections—just power, ground, and signal pin—to begin reading ambient light levels.
Specifications
- Supply Voltage: +5V DC, 50 mA
- Size: 36.5mm x 16mm

Connection Diagram
This component is very straightforward to use: simply connect the power and ground pins, and link the signal pin to your preferred analog input. Once set up, the sensor will output an analog voltage that increases as the light level rises. You also have the option to power it with 3.3V; just note that the output value will be lower in that case.
Sample Code
You can not get more simpler than this – This just reports the reading from the sensor to the serial terminal: 0-1023 with 1023 being very bright, and 0 being very dark.
int temt6000Pin = 0; void setup() { Serial.begin(9600); } void loop() { int value = analogRead(temt6000Pin); Serial.println(value); delay(100); //only here to slow down the output so it is easier to read } |
Result
Wiring well and uploading the code above, open the serial monitor of Arduino software.
Then cover the sensor with your hand or a paper, the light becomes weak, finally you will see the value showed on monitor decrease.
Conclusion
The keyestudio TEMT6000 Ambient Light Sensor is an invaluable tool for anyone looking to incorporate light sensing into their projects. With its precision, ease of use, and wide range of applications, this sensor enhances any electronic system that requires accurate ambient light detection. Whether you are a hobbyist or a professional, this sensor will significantly improve your project capabilities.
