YJJ WF5805F Waterproof Digital Pressure Sensor For Diving Vehicle Logbook

Product Description:

WF5805F Waterproof Digital Pressure Sensor Is Used In Diving Vehicle logbook

Features:

WF5805F is a high-resolution pressure sensor, featuring I²C and SPI interfaces. It includes a silicon piezoresistive pressure element and a high-resolution 24-bit ΔΣ ADC.

The WF5805F offers high-precision 24-bit digital outputs for pressure and temperature. Users can adjust the conversion speed and height according to their application needs. All the built-in calculations employ high-speed 4MHz floating-point operations, resulting in low calculation errors. Data compensation is internally integrated, and the communication connection is very simple.

The WF5805F sensor is packaged with a stainless steel ring surface and the substrate, and complies with RoHS standards. It is extremely small, measuring only 4.5x4.5mm in size and 3.5mm in thickness.
