A sensor in the context of the Internet of Things (IoT) is a device that detects and measures physical parameters from its environment, such as temperature, humidity, motion, or light, and converts them into signals that can be processed, transmitted, or stored.
What is a pressure sensor/pressure transmitter?
A pressure sensor converts the pressureinto a proportional electrical signal (usually 4-20 mA, 0-10 V or digital fieldbus).
What is a pressure switch?
A pressure switch is basically an electrical switch that turns on or off at a preset pressure level. When the thresholdis reached, an internal micro- or macro‐mechanical element (diaphragm, bellows or piezo‐kit) is activated that closes or opens a contact.
Game-Changing New Sensor Could Make Farming More Efficient and Groceries Cheaper
Engineers created a compact sensor with infrared imaging for drones, enhancing crop management by allowing for precise irrigation and pest control, which could lower grocery prices and boost harvests.

4-20 mA Two-Wire Current Loop Basics
Many Gems sensors products offer a linear 4-20 milliamp (mA) output signal for transmitting to a receiver (meter/display, PLC, etc.) when measuring level or pressure. It is good to know the basics when troubleshooting or when choosing the best output signal for your application.
How to Correctly Install and Maintain Pressure Transmitters
The correct installation position of the pressure transmitter on the process pipeline is related to the measured medium. In order to obtain the best measurement effect, the following points should be considered during installation and maintenance:
Types of Pressure Switches and Their Features
There are two main types of pressure switches: mechanical pressure switches and electronic pressure switches. Mechanical pressure switch; Electronic pressure switch
