Introduction

We come across various sensors; one of the most commonly used sensors we all know is a fingerprint sensor. The fingerprint sensor is used in different governments as well as private organizations. For example: when you go for aadhar card registration or pan card registration, the officer asks you to put your fingers on the fingerprint sensor so that they can give you unique recognition.

Not only fingerprint sensors, but there are also various types of sensors, and today, we will discuss one of the sensors, the pressure sensor, specifically the BMP pressure sensor (Barometric Pressure Sensor).

Definition

An IoT pressure sensor is a device that senses pressure and converts it into an electric signal. The level of voltage given out by the sensor depends on the pressure level applied.

BMP pressure sensors enable IoT systems that monitor systems and devices that are pressure propelled. If there’s any deviation from standard pressure ranges, the device notifies the administrator of the problem.

These are commonly found and used to maintain whole water and heating systems. This is because they can easily detect any fluctuations or drops in pressure. However, pressure sensors are used within the manufacturing industry too.

Popular IoT pressure sensor manufacturers include:

  • L-com
  • NCD
  • Omron
