Tiger TKJP040 40 kPa Gauge Pressure Sensor - Digital UART Output

The TKJP040 outputs pressure data via a digital UART (Universal Asynchronous Receiver/Transmitter) serial interface. This provides a direct TTL-level serial data stream, making it simple to connect to microcontrollers like Arduino, ESP32, or Raspberry Pi using a standard RX/TX UART pin pair without requiring an external ADC.

The sensor operates from a supply voltage of 3.3V to 5V DC. This wide range allows compatibility with both 3.3V logic systems (common on modern microcontrollers) and traditional 5V Arduino boards. Ensure your power source is stable and within this range for accurate sensor performance.

The sensor transmits calibrated pressure data packets over UART. You will need to read the serial data stream on your microcontroller and parse it according to the sensor's communication protocol (typically documented in a datasheet). The reading will correspond to the gauge pressure in its configured unit (e.g., kPa or Pa), relative to atmospheric pressure.

Yes, the TKJP040 gauge pressure sensor is suitable for hydrostatic liquid level sensing. By submerging the sensor's pressure port at a certain depth, the measured pressure can be converted to liquid height (level) using the fluid's density. Ensure the sensor's diaphragm and housing are compatible with the liquid media to prevent damage or corrosion.

Yes, the Tiger TKJP040 is factory calibrated for gauge pressure and includes built-in temperature compensation circuitry. This compensation actively corrects for thermal effects across the full -40°C to +85°C operating range, ensuring stable and accurate readings without requiring user calibration or external compensation algorithms.
