Product Description

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.
