Function
The sensor can transfer the measurement signals of temperature, pressure and liquid level to I2C digital output. With the fast and accurate interface, the sensor is used to build an Internet of Things using a microcontroller. It can read data and control power on and off to reduce power consumption through microprocessor operation.Feature
- Digital compensation for sensor offset, sensitivity, temperature drift and nonlinearity
- 32-bit customer ID field for module traceability
- Digital output of temperature and pressure in I2C bus mode
- Fast power-on to data output response: 3ms
- Low power consumption, sleep mode operation, as low as 5 μ A, current consumption depends on the programmed sampling rate
- Operating temperature: -40°C to + 85°C
- Wide supply voltage capability: 3.3V/5V

Data measurement acquisition operation
1. For read and write operations, the master device commands to start, and sends an ACK(acknowledgement) as a slave device to indicate success. The factory address of the slave device is 0x28, and the communication sequence is shown in Figure 3.
2. Read data sequence is as follows(Figure4, 5)
