OnlineSensors Ltd specialises in the design, manufacture, distribution, and supply of a popular range of 0.5 to 4.5 V pressure sensors, with specifications suited to most applications.

We manufacture our own range of pressure sensors in the UK as well as distribute high-quality 0.5 to 4.5V ratiometric pressure sensors.

The 0.5 to 4.5 V output format is widely used across our own and our many customers projects and applications due to their excellent compatibility with low-power embedded systems and IoT solutions.

Whether you’re developing low-power devices, sensor networks, or industrial control systems, our 0.5–4.5 V pressure sensors deliver broad compatibility and simple integration.

We ship worldwide and offer sensors across a wide range of prices and specifications, making it easy to find the right solution for your application and budget.

Designed and supplied from the UK with fast dispatch and expert support, our sensors help reduce development time and give you confidence in your measurements.

0.5 to 4.5 Pressure sensor applications

0.5 to 4.5V is an ideal output for low power and low voltage applications 

• IoT
• Arduino Pressure sensor
• Embedded Pressure sensing
• Low Power
• PLC 

0.5 to 4.5V Pressure Sensor Output 

Example 1 Power Supply 5V

• 0% Pressure = 0.5V or 10% of supply
• 50% Pressure = 2.5V or 50% of supply
• 100% Pressure = 4.5V or 90% of supply

Example 2 Power Supply 3.3V

• 0% Pressure = 0.33V or 10% of supply
• 50% Pressure = 1.65V or 50% of supply
• 100% Pressure = 2.97V or 90% of supply
