Product description: Pressure sensor - 20 kg round 7.5 mm - Joy-IT SEN-Pressure20
The SEN-Pressure20 is a highly sensitive pressure sensor utilizing analog resistance measurement technology . As pressure increases, the resistance of the sensing element changes, which translates into a voltage change at the analog output. This allows for precise monitoring of load, pressure force, or contact with a surface within a range from 0 kg to 20 kg . The sensor features a flexible and waterproof measuring surface less than 0.25 mm thick . The sensor is resistant to electrostatic and magnetic interference, allowing it to operate in demanding environments. The module is compatible with popular microprocessor platforms and can be used in both simple educational projects and advanced automation and robotics systems.
Pressure sensor - 20 kg round 7.5 mm - Joy-IT SEN-Pressure20.
The measuring part (marked in red) is 7.5 mm in diameter.
Main features of the pressure sensor
- Measuring range from 0 kg to 20 kg : possibility of measuring pressure and load in a wide range
- Analog voltage output : easy data reading by microcontrollers and ADC modules
- High measurement sensitivity : quick response to pressure changes
- Flexible design : can be installed in non-standard designs and mobile devices
- Waterproof sensor surface : greater resistance to environmental conditions
- No electrostatic or magnetic interference : stable operation in various applications
- Fast response time of less than 1 ms : quick detection of pressure changes
- High durability : lifespan up to approximately 1,000,000 measurements
Sensor pinouts and connection method
The SEN-Pressure20 module features three pins for quick connection to microprocessor platforms and embedded systems. The "+" pin supplies a voltage between 3.3V and 5V , the "I" pin provides ground , and the "S" pin provides an analog voltage signal corresponding to the current pressure. For Arduino, the sensor can be connected directly to analog input A0 . The Raspberry Pi lacks native analog inputs, so proper operation requires an analog-to-digital converter (ADC) , such as the ADS1115. Thanks to its simple analog interface, the module can be easily integrated into both simple educational projects and more advanced automation systems.
The Raspberry Pi does not have analog inputs, so an analog-to-digital converter is required.
In the case of Arduino, the sensor can be connected directly to the analog input.
Sensor Compatibility, Connectivity, and Programming
The SEN-Pressure20 works with popular development platforms such as Arduino, Raspberry Pi, ESP32, and other microcontrollers equipped with analog inputs or external ADCs . The sensor can be controlled using the Arduino IDE, MicroPython, CircuitPython, and standard Python libraries for the Raspberry Pi . The manufacturer provides ready-made code examples for reading voltage values and calculating sensor resistance based on the measured analog signal.
