Tiger TK1300B 1000KPa Gauge Pressure Sensor - Digital UART Output

The TK1300B provides a fully digital output via a UART serial interface (TTL logic levels). This means it sends calibrated pressure data as serial data packets, making it straightforward to read with any microcontroller that has a UART port, such as Arduino, ESP32, or Raspberry Pi, without needing an external ADC.

Gauge pressure measures pressure relative to the ambient atmospheric pressure. The TK1300B is a gauge pressure sensor, meaning its zero point is atmospheric pressure. It is ideal for applications like pneumatic system pressure, liquid level (open tank), or air flow where you need to measure pressure above or below the local environment.

Connect the sensor's VCC (3.3-5V) and GND pins to your power supply. Connect its TX pin to the RX pin of your microcontroller's UART, and its RX pin to the microcontroller's TX pin if you need to send commands (though often only reading is required). Use standard serial communication libraries to parse the data packets sent by the sensor at its configured baud rate.

No, the Tiger TK1300B is factory-calibrated and includes on-chip temperature compensation. It is ready for use upon power-up, outputting a calibrated digital pressure value. No user calibration is typically required unless extreme accuracy verification is needed for a specific application.

The sensor's rated pressure range is 0-1000 kPa (0-1 MPa). It can withstand a maximum pressure (overpressure) of 1 MPa without causing permanent damage or failure, ensuring a safety margin for transient pressure spikes in your system.
