Tiger TKPS1700 Pressure Sensor 0-400 kPa Absolute Pressure - I2C/UART Digital Output

The TKPS1700 is configured as an absolute pressure sensor, meaning it measures pressure relative to a perfect vacuum (zero pressure reference). This is distinct from gauge pressure, which is measured relative to ambient atmospheric pressure. Absolute pressure readings are essential for applications like altitude measurement, barometric pressure sensing, and sealed tank monitoring where an external reference is not available.

Interfacing is straightforward via the digital I2C or UART interface. For I2C, connect the sensor's SDA and SCL pins to the corresponding pins on your microcontroller, along with VCC (3.3V-5V) and GND. Use standard I2C library functions to read data. For UART, connect the TX/RX pins to a serial port on your MCU and use serial communication libraries. The sensor comes pre-calibrated, so no additional setup is required.

The 2 MPa (approximately 290 psi) maximum pressure rating indicates the sensor can withstand short-term overpressure up to this level without sustaining permanent damage or calibration shift. This provides a significant safety margin over its normal 400 kPa operating range, ensuring robustness against pressure spikes or surges commonly encountered in industrial environments, thereby enhancing long-term reliability.

No, external compensation or calibration is not required. The TKPS1700 features built-in, on-chip temperature compensation that is active across its full -40°C to +85°C operating range. The sensor is factory-calibrated, providing accurate digital output readings immediately upon power-up, which simplifies integration and reduces development time for your pressure monitoring system.
