CJMCU-MS5540CM MS5540C Digital Pressure Sensor Module Waterproof 100m

Product Description

The CJMCU-MS5540CM Digital Pressure Sensor Module is a high-precision, waterproof pressure and temperature sensor designed for underwater and environmental monitoring applications. With a measurement range of 10 to 1100 mbar, resolution of 0.1 mbar, and temperature resolution of 0.01°C, it is ideal for altimeters, depth gauges, weather stations, and diving projects.

This compact sensor features a piezoresistive silicon microsensor, a 16-bit ADC, and supports SPI and 3-wire serial interfaces for reliable digital communication. Its ultra-low power consumption (<5 µA) and operating voltage of 2.2V–3.6V make it suitable for battery-powered systems.

Waterproof up to 100 meters depth, the MS5540C module ensures durability and precision in harsh environments.
