Tiger TK1300B 250KPa Digital Pressure Sensor - UART Output, Gauge Pressure

The sensor outputs data via a digital UART serial interface. To connect it to an Arduino, you would link the sensor's TX pin to an RX pin on the Arduino (e.g., SoftwareSerial pin) and the sensor's RX pin to an Arduino TX pin. Ensure a common ground and power the sensor within its 3.3V to 5V DC range. The sensor transmits pre-formatted data packets that can be parsed with standard serial read functions.

Gauge pressure measures pressure relative to the local atmospheric pressure, while absolute pressure is measured relative to a perfect vacuum. The TK1300B is a gauge pressure sensor, meaning its zero point corresponds to ambient atmospheric pressure. This makes it suitable for applications like monitoring pneumatic system pressure, HVAC duct pressure, or liquid level where the reference is the surrounding environment.

Yes, the integrated intelligent chip provides factory calibration and built-in temperature compensation across the -40°C to +85°C range. This means the digital output readings are directly usable without requiring additional user calibration or external compensation circuits, enabling plug-and-play integration into your system.

The sensor has a maximum pressure rating of 1 MPa (approximately 10 bar or 145 psi). This is the pressure limit it can be exposed to without causing permanent damage or failure. The operational measuring range is 0-250 kPa, and exceeding the 1 MPa maximum pressure may permanently degrade sensor accuracy or cause physical damage.
