Product description: Gravity - 5 mm slot sensor module - ITR9608 - 940 nm - DFR1129
The DFRobot Gravity module based on the ITR9608 sensor offers high sensitivity and precision in object detection. The operating principle is based on the interruption of a 940 nm infrared light beam, which generates a digital signal. Thanks to a 5 mm optical gap , it can detect various sizes of objects. The module supports voltages from 3.3 V to 5 V and is equipped with a Gravity interface, which ensures easy integration with the Arduino , micro:bit and UNIHIKER platforms. The compact design and fast response time make it perfect for automation, robotics and energy-saving devices.
The manufacturer has prepared a detailed user guide that will help you get started with the module - check it out!
Gravity - 5 mm slot sensor module - ITR9608 - 940 nm - DFR1129.
Module based on the ITR9608 sensor.
Main features of the module
- Precision sensor: ITR9608 for reliable object detection
- Wide optical aperture: 5 mm allows detection of objects of various dimensions
- Fast response time: ideal for real-time applications
- Ease of use: Gravity interface makes it easy to connect and configure
- Wide compatibility: works with Arduino, micro:bit and UNIHIKER
How to connect Gravity module to Arduino Uno?
Connecting the module to the Arduino Uno is intuitive thanks to the standard Gravity interface.
- Power supply: the module uses 5V power from Arduino (VCC) and ground (GND), which is typical for most digital sensors
- Output signal: the digital output of the module is connected to P7. Detection of an obstacle in the sensor slot generates a high signal (HIGH), which is read by Arduino
- LED module: the example project uses an LED module, connected to P4, which acts as an indicator - it lights up when the slot sensor detects an obstacle
After assembling the system, you need to upload the appropriate code to Arduino so that the modules work in synchronization, e.g. by signaling the detection of an obstacle with an LED. Thanks to its simplicity and standardized interface, this module is perfect for beginners and advanced users.
Interrupting the infrared light beam generates a digital signal.
