The MPS31 is a family of pressure, temperature, and humidity sensors from Honeywell. It is designed for both indoor and outdoor installations. The devices use a piezoresistive sensing element to measure pressure, temperature, and humidity, and a variety of digital outputs, such as standard I2C, to provide accurate measurements. The MPS31 can measure pressure up to 500 mbar, temperature up to +125°C and humidity up to 100 percent. The devices are ideal for use in applications like medical devices, HVAC systems, and industrial equipment where accuracy and reliability are essential.
