 +The **CFSensor XGZP68xx series** features high-performance silicon pressure sensors combined with an ASIC for calibration and temperature compensation. 
 + 
 +Silicon pressure sensors typically use one of two main methods: 
 + 
 +**Piezoresistive:** Resistors are placed on a thin silicon diaphragm. When pressure bends the diaphragm, the resistance changes, which is measured as a voltage. 
 + 
 +**Capacitive:** Pressure changes the distance between two plates (one of which is a silicon diaphragm), altering the electrical capacitance.

 +**Key Selection Guide** 
 + 
 +  * **For Arduino/ESP32:** Stick to the //"D"// models (Digital I²C) to avoid external ADC calibration and reduce wiring. 
 +  * **For Ultra-Low Pressure:** Use the XGZP6810D for sensitive tasks like HVAC air flow or medical ventilators. 
 +  * **For Liquid/Vacuum:** The XGZP6859D is specifically designed for vacuum detection with a barb inlet. 
 +  * **Analog Preference:** If your system lacks I2C, the XGZP6899A is the analog version of the 6899D. 
 + 
 +**Note:** Always check the voltage suffix (e.g., 33 for 3.3V or 50 for 5.0V) to match your microcontroller logic levels.

 +**XGZP6847D** 
 + 
 +{{ :sensor:xgzp6847a_1.png?120|XGZP6847A}} 
 +The **XGZP6847D** is a fully calibrated silicon pressure sensor module designed for air and non-corrosive gases. It combines a MEMS pressure die with an integrated ASIC to provide direct digital readings via I²C, eliminating the need for complex external amplification or calibration. 
 + 
 +**Technical Specifications** 
 + 
 +  * **Pressure Range:** Covers a vast span from -100kPa to 1500kPa (model-specific). 
 +  * **Accuracy:** Typically ±2% FSS (Full Scale Span) for ranges between 10kPa and 200kPa, and ±2.5% FSS for other ranges. 
 +  * **Resolution:** 21-bit for pressure and 16-bit for temperature readings. 
 +  * **Power Supply:** Operates between 2.5V and 5.5V DC, with a default test voltage of 3.3V. 
 +  * **Current Consumption:** Very low, typically around 1.8mA during active measurement and as low as 100nA in standby. 
 +  * **Temperature Compensation:** Calibrated for accurate performance between 0°C and +60°C.
