Digital Output Pressure Sensor-Atech Sensor Co., Ltd.

Products Description

Digital Pressure Sensor can transfer the measurement signals of pressure and liquid level to IIC digital output. With the fast and accurate interface, the ESS319-IIC 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.

It ranges from -100KPa to 100MPa.

Applications：

● Industrial process control

● Level measurement

● Gas, liquid pressure measurement

● Pressure checking meter

● Liquid pressure system and switch

● Pressure calibrator

● Cooling equipment & A/C system

● Aviation and navigation inspection

Product Features

● 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 uA,
